Multi-channel Half Bridge Driver

Datasheet (EN) 1.3

Product Overview

Key Features



6x half bridge driver

The NSD8306/NSD8306A is a multi-channel half-bridge

driver for automotive applications including HVAC flap DC

motors, side mirror adjustment / fold motors, general

relays, or other LEDs.

1A per HB channel, 3A max for all channel all on

Half bridge output can be in parallel



AEC-Q100 Grade1 Qualified

With the different connection configuration of half-bridge

power stage outputs, the device can driver DC motors in

simultaneous, sequential, or parallel mode. The outputs

also support DC motor in forward, reverse, slow decay, and

fast decay operation.

Wide 4.5V to 36V (configurable) operating Voltage

Very low quiescent sleep mode

PWM mode with internal PWM generation on each channel

4 PWM frequency options: 80/100/200/2000 Hz

Duty cycle 8-bit resolution (1/255, ~0.4 % duty)

The device includes 6x internal configurable PWM

generators, which allow for flexible control for LED

dimming or motor current limitation during start up or stall

condition.



Integrated diagnosis and fault protection features

VM undervoltage & overvoltage protection (UV&OV)

Overcurrent / short circuit Protection (OCP/SCP)

Over temperature warning & shutdown

Open load diagnosis

The integrated serial peripheral interface (SPI) controls all

outputs and provides diagnostic information including

normal operation, POR, VM undervoltage/overvoltage,

overcurrent, over temperature protection and open load

status.

Dedicated nFault indicator pin



HB output Slew rate control two options:

0.6V/ s(default) / 2.5V/µs

The device features sleep mode with low quiescent current

when EN input is low or VDD falls below POR threshold.
