Name

Function

CSN

SPI: chip select not input

TXDL

LIN transmit data input

RXDL/NINT

RXDL -> LIN receive data output; NINT -> indicates local/remote wake-up events

TXDC

CAN transmit data input

RXDC

CAN receive data output (push pull output stages)

PWMH

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

DIRH

Direction Input: this input controls the H-bridge drivers for the external Power MOSFETs

NRESET

Power GND NReset output to microcontroller; internal pull-up of typical 110 kΩ (reset state = LOW) (open drain

output stage)

N.C.

Not connected

5V_1

Voltage regulator output: 5 V supply for example microcontroller, CAN transceiver

CAN_SUP

CAN supply input; to allow external CAN supply from V1

CAN_L

CAN low level voltage I/O

CAN_H

CAN high level voltage I/O

N.C.

Not connected

Debug

Debug input to deactivate the window watchdog (active high). Voltage capability linked to VS

LIN

LIN bus line

5V_2

Voltage regulator output: 5 V supply for external loads (potentiometer, sensors). V2 is protected against reverse

supply

GL1

Gate driver for Power MOSFET low-side switch in half bridge 1

SH1

Source of high-side switch in half bridge 1

GH1

Gate driver for Power MOSFET high-side switch in half bridge 1

GH2

Gate driver for Power MOSFET high-side switch in half bridge 2

SH2

Source of high-side switch in half bridge 2

GL2

Gate driver for Power MOSFET low-side switch in half bridge 2

DIR1/EI2

DIR1 -> direct HS drive 1;

EI2 -> input pin for static or cyclic monitoring of external contacts
