... Theory of Operation The MX8830 family are dual MOSFET drivers, designed to drive two external N-channel power MOSFETs. The low-side driver is designed to drive a non-floating N-channel power MOSFET and its output is out of phase with the PWM input. The high-side driver is designed to drive a floating N- channel power MOSFET and its output is in phase with the PWM input ...

... Side Gate Driver so the switching current can be minimized. Shutdown For optimal system power management, the MX8830R/X drivers can be shut down to conserve power. When the SD pin is high, the MX8830R/X are enabled for normal operation. Pulling the SD MX8830 Drawing No. 0883009 MX883B/MX883R/MX883X pin low forces the HGD and LGD outputs low, and reduces the supply current by disabling the internal reference ...
