On semiconductor s high voltage process and common mode noise canceling technique provide stable operation of high drivers under high dv dt noise circumstances. These include under and over voltage monitors for the power supply and charge pump vds overcurrent and vgs gate fault monitors for the external mosfet and. Featured low side driver devices ucc27511a single channel high speed low side gate driver with 4 a peak source and 8 a peak sink. The drv8705s q1 provide an array of protection features to ensure robust system operation.

A shunt amplifier provides low side current sensing to continuously measure motor current. Temperature grade 1. However if i connect the gate driver s ground to high side of the sense resistor that means that the reference for the input to the driver will move with source current. It also includes a pull down resistor and an input schmitt trigger for better noise immunity.
