Dual High Side Switch for H-Bridge Automotive Applications
This device is a dual high side switch for automotive applications which incorporates a dual low side switch control feature. This device is designed to monitor two low side switches for typical DC-motor control in an H-Bridge configuration. It can be directly interfaced with a microcontroller for control and diagnostic functions, is PWM capable and has a self-adjusted switching speed for minimizing electromagnetic emission. The High Side block incorporates two 15mΩ Rdson N-Channel power Mosfets with senses and a control circuitry.
