uP1951P
uPI Semiconductor
12V MOSFET Drivers with Output Disable
Package Type: WQFN3x3 - 16L
The uP1951 is a quad, high voltage MOSFET driver optimized for driving four N-Channel MOSFETs in a dual synchronous-rectified buck converter. Each driver is capable of driving a 5000pF load with 30ns transition time. This device combined with uPI multi-phase buck PWM controller forms a complete core voltage regulator for advanced micro-processors. The uP1951 features adaptive anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintaining minimum deadtime for optimized efficiency. Both gate drives are turned off by pulling low OD# pin or high-impedance at PWM pin, preventing rapid output capacitor discharge during system shutdowns. Other feature is supply input under voltage lockout. The uP1951 is available in thermal enhanced WQFN3x3-16L package.
