The ADM1200 is an NFET driver with a programmable slew rate control system that ensures that the output voltage rises and falls at a controlled rate and in a linear fashion.
The ADM1200 is an N-channel FET driver designed to enable power supply tracking of multiple supplies with a capacitor-adjustable linear slew rate. It features an on-board charge pump that fully enhances NFETs, allowing the output voltage to follow the SLEW pin within approximately 100mV. The device can be cascaded to form multi-supply tracking solutions for various applications including network processors and PC/server systems.
