Infineon introduces -1A/2A, 160V MOTIX three-phase SOI grid driver

Integrated bootstrap diodes are used to power three external high-edge charging bootstrap capacitors, which support 100% duty cycle conditions through trickle charging pumps. Protection features include undervoltage locking, overcurrent protection with configurable thresholds, fault communication, and automatic fault signal clearing. Driver output with a pulse large current buffer stage minimizes driver cross - conduction. A current sensing operational amplifier (CSA) with selectable gain is integrated between VSS and COM.

The drive is a simple, easy to use and cost-effective one-stop solution for a variety of battery-powered applications such as power tools, robotics and light electric vehicle LeVs.
