Analog Integrated Circuit Device Data
8 Freescale Semiconductor
10XSC425
8, 25 GND Ground Ground
These pins, internally shorted, are the ground for the logic and analog circuitry
of the device. These ground pins must be also shorted in the board.
9, 33 VPWR Power Positive Power Supply
This pin connects to the positive power supply and is the source of operational
power for the device. Pins 9 and 33 must be externally connected.

HS3 Output High Side Output
Protected 25 m high side power output pins to the load.
14, 15, 16 HS1 Output High Side Output
Protected 10 m high side power output pins to the load.
17, 18, 19 HS0 Output High Side Output
Protected 10 m high side power output pins to the load.
20, 21, 22,
23
HS2 Output High Side Output
Protected 25 m high side power output pins to the load.
24 NC N/A No Connect
This pin may not be connected.
26 FSI Input Fail-safe Input
This input enables the watchdog timeout feature.
27 CSNS Output Output Current
Monitoring
This pin reports an analog value proportional to the designated HS[0:3] output
current or the temperature of the GND flag (pin 14). It is used externally to
generate a ground-referenced voltage for the microcontroller (MCU) . Current
recopy and temperature feedback is SPI programmable.

Input Direct Inputs
Each direct input controls the device mode. The IN[0 : 3] high side input pins
are used to directly control HS0
: HS3 high side output pins.
The PWM frequency can be generated from IN0 pin to PWM module in case
of external clock is set.
32 FSB Output Fault Status
(Active Low)
This pin is an open drain configured output requiring an external pull-up
resistor to VDD for fault reporting.
