uP1959T-MD中文资料12V Single Channel MOSFET Driver数据手册uPI(UBIQ)规格书

描述 Description

The uP1959T is a dual, high voltage MOSFET driveroptimized for driving two N-channel MOSFETs in asynchronous-rectified buck converter. Each driver iscapable of driving a 5000pF capacitive load with 30nstransition time. This device combined with uPI multi-phasebuck PWM controller forms a complete core voltageregulator for advanced micro-processors.

The uP1959T features adaptive anti-shoot-through protectionthat prevents cross-conduction of the external MOSFETwhile maintains minimum deadtime for optimized efficiency.This part has integrated bootstrap diode to help minimizethe external component count. Both gate drives are turnedoff by pulling low OD# pin or high-impedance at PWM pin,preventing rapid output capacitor discharge during systemshutdown.

This device also supports supply input under voltagelockout. The uP1959T is available in thermally enhancedWDFN3x3 - 8L package.
