Functional Description

2.2.2.1 Primary Side

GND1

Ground connection for the primary side.

VCC1

5V power supply for the primary side (referring to GND1).

INP

Non-inverting PWM input of the driver. The internal structure of the pad makes the IC robust against glitches. An

internal weak pull-down resistor to VREF0 drives this input to Low state in case the pin is floating.

INSTP

Monitoring PWM input for shoot through protection. The internal structure of the pad makes the IC robust against

glitches. An internal weak pull-down resistor to VREF0 drives this input to Low state in case the pin is floating.

REF0

Reference Ground signal for the signals INP, INSTP, EN/FEN. This pin should be connected to the ground signal

of the logic issuing those signals.

EN/FEN

Enable Input Signal. This signal allows the logic on the primary side to turn-off and deactivate the device. An

internal weak pull-down resistor to VREF0 drives this input to Low state in case the pin is floating. This pin reacts

on logic levelsor on a periodic signal, depending on the deviceâs configuration.

NFLTA

Open-Drain Output signal used to report major failure events (Event Class A). In case of an error event, NFLTA

is driven to Low state. This pin shall be connected externally to VCC1 with a pull-up resistance.

NFLTB

Open-Drain Output signal used to report major failure events (Event Class B). In case of an error event, NFLTB

is driven to Low state. This pin shall be connected externally to VCC1 with a pull-up resistance.

SCLK

Serial Clock Input for the SPI interface. An internal weak pull-up device to VCC1 drives this input to high state in

case the pin is floating.

SDO

Serial Data Output (push-pull) or the SPI interface.

SDI

Serial Data Input for the SPI interface. An internal weak pull-up device to VCC1 drives this input to high state in case

the pin is floating.
