Description

The 10410 is a high-side driver for automotive applications. It can drive small lamps, relays, coils etc. The output current
can be up to 250mA per driver (current limit at minimum 250mA).

The IC will only react to commands on the bus if the CEN (chip enable) signal is high. The CEN signal has nothing to do
with the power down mode, the IC will react to the micro controller commands if CEN is high.

8 Fold High Side Driver

In order to switch a particular output, it is necessary to apply its address on the 3 bit bus and the data on the input
DATAI. A high level on STROBE will latch the data and switch the output. When the IC is in active mode and CEN is
high, the logic level of the addressed output will be available on the pin DATAO.

When all 8 outputs are inactive (latched value is low) the circuit automatically switches to power down mode.
Diagnostic mode: when the DATAI is low and the STROBE is high, a 50K pull up to VCC is switched on, on the

corresponding output channel (addressed by ADR2, ADR1, ADR0) to see whether there is a load connected. The logic
level of the output can be observed on the pin DATAO. In this way, it is possible to scan all the outputs for an open
circuit.

When the IC is in active mode, then there is an over-temperature sensor that monitors the temperature of the IC. If the
die temperature goes above 165°C, all outputs are switched off and the output OTB will go low. As soon as the
temperature decreases below 125°C all outputs are switched back to their previous state.

The outputs are short-circuit proof against GND and VCC. When an output is shorted to GND, the current is limited and,
after a delay of typically 20ms, the output is switched off and the output OTB goes low. A delay is used to guarantee that
the output does not detect a short circuit when a normal lamp is driven. The latched value of the ouput is set to 0. A
rising edge on CEN will set OTB back to 1. When an output is shorted to a supply larger than VCC+100mV, the output
driver bulk is immediately disconnect from VCC, and after a delay of typically 20ms, the output is switched off and the
output OTB goes low. The latched value of the ouput is set to 0. A rising edge on CEN will set OTB back to 1

There is an over-voltage shut off that switches all the outputs off when the VCC voltage is above 18V for at least 1ms.
When an over-voltage occurs, CEN being low, DATAO pin will go low. The outputs will come on again as soon as the
voltage decreases below 18V. The status of all 8 outputs stays latched.
Every output stage is protected with a free wheel diode both to ground and to VCC.
