Outputs
There are 2 types of outputs on the DPS70. There are two high-side outputs and a
5V sensor supply output.
▪ High-side outputs
▪ Sensor supply output
3.1. High-Side Outputs
The DPS70 has 2 high-side outputs:
▪ High-Side Output 1 to High-Side Output 2
High-side outputs are used for switching voltages to loads using either a pulse
width modulated (PWM) signal, or an on/off signal. They can also test for various
fault conditions.
3.1.1. High-Side Output Capabilities
All high-side outputs come with internal flyback diodes that provide protection
when driving inductive loads.
▪ When a high-side output is used as a PWM signal, a pulsed output signal is
provided by the DPS70, where the percentage of time that the output is “on”
vs. “off” is determined by the duty cycle of the signal. The duty cycle is
determined by the software
▪ When a high-side output is used as an on/off signal, the output provides
battery voltage when in the “on” state (the software is responsible for
switching high-side outputs on and off)

3.1.2. High-Side Output Configuration Options
The DPS70 high-side outputs may be configured with a software controlled 10
k pull-up resistor to battery for open load detection in the off state.
3.1.3. High-Side Output Installation Connections
When connecting the high-side outputs, note that:
▪ The high-side output is connected to an internal bus bar, which can be
connected to a +12 V or +24 V battery
▪ The high-side output can provide switched battery power to any load type in a
vehicle
▪ The high-side output has an internal flyback diode to absorb electrical energy
when the load is turned off
When connecting high-side outputs:
▪ Connect the load grounds close to the power grounds
▪ Do not connect high-side outputs to loads that will draw currents greater than
the maximum peak current or maximum continuous current

Figure 5: Typical high-side output installation connections
The high-side driver is self-protecting and will shut off during a short circuit or if
an over temperature condition occurs. When the condition clears, the output
driver automatically tries to turn on the load.
Damage to equipment! Repeated cycling into a short circuit could
potentially lead to damage.
The output will be latched off if a short circuit or over temperature fault occurs. A
software cycling of the output driver state is required to turn the output on again.
3.1.4. High-Side Output Diagnostics and Fault Detection
The DPS70 high-side outputs have the ability to report many different fault
conditions. They are protected against short-circuit, overcurrent, open load, shortto-battery and short-to-ground faults.
3.1.4.1. Short Circuit
Short-circuit faults occur when a low-side output pin is shorted to battery and
produces an output current above the specified over-current trip point, causing an
over-current on the circuit.
When a short circuit or over-current fault is detected, the software automatically
turns off the output.
The short circuit trip time for low-side outputs depends on how the outputs are
configured.
The application software can be used to reset an output from a short circuit or an
over-current fault by turning the output off and then on again.
Page 23
User Guide 15
Outputs
3.1.4.2. Overcurrent
Overcurrent faults occur when a low-side output pin draws more current than the
specified overcurrent trip point.
When an overcurrent fault is detected, the hardware automatically turns off the
output.
The overcurrent trip time for low-side outputs is approximately 1 second.
Note: The DPS70 can be programmed to automatically reset an output from
an overcurrent fault.
3.1.4.3. Open Load
Open load faults occur when a high-side output pin is open circuit (not connected
to a load). The high-side output circuit uses a small amount of current on the
output pin to determine if an open load condition exists.
High-side outputs with current sense can detect an open load fault when on or off.
High-side outputs without current sense must be off to detect an open load fault.
3.1.4.4. Open Load
Open load faults occur when a low-side output pin is open circuit (not connected
to a load). The use of this feature operates as defined by the programmer
The low-side output circuit uses a small amount of current on the output pin to
determine if an open load condition exists.
Note: Low-side outputs must be on to detect an open-load fault.
3.1.4.5. Short-to-Battery
Short-to-battery faults occur when a high-side output pin is connected to battery
voltage.
The high-side output circuit uses voltage on the output pin to determine if a shortto-battery condition exists.
Note: High-side outputs must be off to detect a short-to-battery fault.
3.1.4.6. Short-to-Ground
Short-to-ground faults occur when a low-side output pin is connected to ground.
The low-side output circuit uses a small amount of current on the output pin to
determine if a short-to-ground condition exists.

Outputs
3.2. Sensor Supply Output
The DPS70 has 2 pins, labeled SENSOR_SUPPLY and SENSOR_GND, dedicated to
providing power to external sensors.
Warning! Do not drive more than 100 mA of current through the
SENSOR_SUPPLY pin. Doing so will cause the pin to protect itself by
dropping the voltage, which will result in a lack of power to the sensors,
causing unknown vehicle responses.
3.2.1. Sensor Supply Output Capabilities
SENSOR_SUPPLY is a 5 V linear power supply that is capable of continuously
providing 100 mA to external sensors.

3.2.2. Sensor Supply Output Installation Connections
The sensor supply and the sensor ground are intended to be the power source for
external sensors. It is important that these power signals do not connect to another
power source or ground external to the DPS70.
3.2.3. Sensor Supply Output Diagnostics and Fault
Detection
The sensor supply voltage is monitored as an analog channel. This allows for
increased accuracy of external sensors that are connected to the supply, and also
permits fault detection from short circuit to the supply.

User Guide 17
Power
The DPS70 operates in a 12 V or 24 V system and is powered by a direct battery
connection. The direct battery input is protected against vehicle transients. It is
also protected against reverse battery voltage and abnormal high battery voltage
by shunting the internal current to ground and blowing the automotive fuse that
must be designed into the power circuit in the end system application.

▪ 6 LEDs are RGB with feedback
▪ 6 LEDs are RGB
▪ 2 LEDs are Green
▪ 2 LEDs are Amber
▪ 6 LEDs are Red
▪ 1 LED is Blue
▪ 3 LEDs are Red for analog gauge warnings
Note: The tricolor LEDs have the red/green brightness ratio set so that they
provide an amber color similar to that of the individual amber LED. As
a result, when all three colors in the tricolor LED are turned on, the
color is not white.
The icons associated with each status LED are determined by the overlay. The
default overlay is shown above, but it can be customer-specific.
