Programmable 16−Channel Low-Side Driver with SPI and Load Current Sensing

Skip to the beginning of the images gallery

The HI-84216 is a smart 16-channel low-side driver designed for high-reliability applications. The device uses a Serial Peripheral Interface (SPI) for intelligent switch control, monitoring and advanced diagnostics.

The HI-84216 is capable of sinking 250mA per channel with up to 4A total sink current for parallel channel operation. An 8-bit ADC provides accurate measurement of channel current and temperature while an internal PWM clock generator with 16-bit resolution provides application flexibility.
