Applications
■ Door actuator driver with 6 bridges for double
door lock control, mirror fold and mirror axis
control, highside driver for mirror defroster,
bulbs and LEDs (replacement for L9950).
Control block with external MOS transistor for
charging / discharging of electrochromic glass.
Description
The L99DZ70XP is a microcontroller driven
multifunctional door actuator driver for automotive
applications. Up to five DC motors and five
grounded resistive loads can be driven with six
half bridges and five highside drivers. An
electrochromic mirror glass can be controlled
using the integrated SPI-driven module in
conjunction with an external MOS transistor. The
integrated SPI controls all operating modes
(forward, reverse, brake and high impedance).
Also all diagnostic information is available via SPI
read.

Important: For the capability of driving the full current at the outputs all pins
of GND must be externally connected!
Highside driver output 11.
The output is built by a highside switch and is intended for resistive loads,
therefore the internal reverse diode from GND to the output is missing. For
ESD reason a diode to GND is present, but the energy which can be
2, 35 OUT11
dissipated is limited. The highside driver is a power DMOS transistor with an
internal parasitic reverse diode from the output to VS (bulk-drain-diode). The
output is over-current protected.
Important: for the capability of driving the full current at the outputs both pins
of OUT11 must be externally connected!

Halfbridge outputs 1,2,3.
The output is built by a highside and a lowside switch, which are internally
connected. The output stage of both switches is a power DMOS transistor.
Each driver has an internal parasitic reverse diode (bulk-drain-diode:
highside driver from output to VS, lowside driver from GND to output). This
output is over-current protected.
Power supply voltage (external reverse protection required).
For this input a ceramic capacitor as close as possible to GND is
recommended.
S
Important: For the capability of driving the full current at the outputs all pins
of VS must be externally connected!
Serial data input.
The input requires CMOS logic levels and receives serial data from the
microcontroller. The data is a 24 bit control word and the most significant bit
(MSB, bit 23) is transferred first.
Current monitor output/PWM2 input.
Depending on the selected multiplexer bits of the control register this output
sources an image of the instant current through the corresponding highside
driver with a ratio of 1/10.000 or 1/2000. This pin is bidirectional. The
microcontroller can overdrive the current monitor signal to provide a second
PWM input for the outputs OUT5, OUT8 and OUT10.
Chip Select Not input / Testmode.
This input is low active and requires CMOS logic levels. The serial data
transfer between L99DZ70 and the microcontroller is enabled by pulling the
input CSN to low level.
Serial data output.
The diagnosis data is available via the SPI and this tristate-output. The
output will remain in tristate, if the chip is not selected by the input CSN
(CSN = high)
Supply voltage.
12 VCC
For this input a ceramic capacitor as close as possible to GND is
recommended.

This input controls the internal shift register of the SPI and requires CMOS
logic levels.

Halfbridge outputs 4,5,6: see OUT1 (pin 3).
Important: For the capability of driving the full current at the outputs both
pins of OUT4 (OUT5, respectively) must be externally connected!
Electrocromic driver output.
If the electrochrome mode is selected this pin is used to control the gate of
25 ECDR
an external MOSFET, otherwise it remains in high-impedance state.
Note: It is possible to connect the pin to VS as in L9950/53/54 applications,
as long as the electrochome mode is not enabled via SPI.
Charge pump output.
26 CP
This output is provided to drive the gate of an external n-channel power
MOS used for reverse polarity protection (see Figure 1.).

Highside driver outputs 7,8: see OUT9.
By selection of one of the 2 power DMOS at same output is it possible to
supply a bulb with low on-resistance or a LED with higher on-resistance in a
different application.
Electrochrome voltage input and lowside driver output.
This input senses voltage in electrocrome mode for charge monitoring.
The lowside switch provides a fast discharge of electrocromic mirror and can
be used 'stand alone' as lowside switch beside electrocromic mode.
Highside driver output 9.
The output is built by a highside switch and is intended for resistive loads,
hence the internal reverse diode from GND to the output is missing. For
ESD reason a diode to GND is present but the energy which can be
dissipated is limited. The highside driver is a power DMOS transistor with an
internal parasitic reverse diode from the output to VS (bulk-drain-diode). The
output is over-current and open load protected.
Highside driver output 10: see OUT9.
Important: beside the bit10 in control register 1 this output can be switched
on setting bit1 for electrocromic control mode with higher priority.

2.1 Absolute maximum ratings
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality document.
