Description
The VNI8200XP-32 is a monolithic 8-channel driver featuring a very low supply current, with integrated SPI interface and high efficiency 100 mA micropower step-down switching regulator peak current control loop mode. The IC, realized in STMicroelectronics VIPower™ technology, is intended to drive any kind of load with one side connected to ground.
