FDG901D April 2002 FDG901D Slew Rate Control Driver IC for P-Channel MOSFETs General Description The FDG901D is specifically designed to control the turn on of a P-Channel MOSFET in order to limit the inrush current in battery switching applications with high capacitance loads.
During turn-on the FDG901D drives the MOSFET’s gate low with a regulated current source, thereby controlling the MOSFET’s turn on.
For turn-off, the IC pulls the MOSFET gate up quickly, for efficient turn off.
Features • Three Programmable slew rates • Reduces inrush current • Minimizes EMI • Normal turn-off speed • Low-Power CMOS operates over wide voltage range Applications • Power management • Battery Load swit...
