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
