40V 8-channel Half-bridge Driver IC
NSD8308-Q1 is a multi-channel half-bridge driver IC with 8-channel half-bridge structures. Through flexible configuration, the IC can support different load types including brushed DC motors, stepping motors, relays, LEDs, etc. The IC is designed with a built-in PWM generator, which can configure PWM frequency and duty cycle to control load only through SPI, and can be applied to soft start of brush DC motor and LED dimming, etc. At the same time, the product is designed with intelligent diagnosis function to help the vehicle system judge load connection status. In case of disconnection or short circuit, the external MCU can obtain fault reporting information from register built in the IC for each channel.
