PWMH

PWMH input: this input signal can be used to control the H-bridge Gate

Drivers.

DIRH

Direction Input: this input controls the H-bridge Drivers for the external

MOSFETs

DIR2

Direct Drive Input 2

NRESET

NReset output to micro controller; (reset state = LOW) (Low-side switch

with drain connected to the output pin and internal pull up resistance to

5V_1)

5V_1

Voltage regulator 1 output: 5 V supply e.g. micro controller, CAN

transceiver

CAN Supply

CAN supply input; to allow external CAN supply from V1 or V2 regulator

NINT

Interrupt output (low active; push-pull output stage) to indicate VSREG

early warning (Active mode); indicates wake-up events from V1_standby

mode

CAN_L

CAN low level voltage I/O

CAN_H

CAN high level voltage I/O

Debug

Debug input to deactivate the window watchdog (high active)

LIN

LIN bus line

5V_2

Voltage regulator 2 output: 5 V supply for external loads (potentiometer,

sensors) or CAN Transceiver. V2 is protected against reverse supply

GH1

Gate driver for PowerMOS high-side switch in half-bridge 1

GH2

Gate driver for PowerMOS high-side switch in half-bridge 2

SH2

Source of high-side switch in half-bridge 2
