RT9602
RT9602 is Dual Channel Synchronous-Rectified Buck MOSFET Driver manufactured by Richtek.
Description
The RT9602 is a dual power channel MOSFET driver specifically designed to drive four power N-Channel MOSFETs in a synchronous-rectified buck converter topology. These drivers bined with RT9237/A and RT9241A/B series of Multi-Phase Buck PWM controllers provide a plete core voltage regulator solution for advanced microprocessors.
The RT9602 can provide flexible gate driving for both high side and low side drivers. This gives more flexibility of MOSFET selection.
The output drivers in the RT9602 have the capability to drive a 3000p F load with a 40n S propagation delay and 80n S transition time. This device implements bootstrapping on the upper gates with only a single external capacitor required for each power channel. This reduces implementation plexity and allows the use of higher performance, cost effective,N-Channel MOSFETs.Adaptive shoot-through protect-ion is integrated to prevent both MOSFETs from conducting simultaneously.
The RT9602 can detect high side MOSFET drain-to-source electrical short at power on and pull the 12V power by low side MOS and cause power supply to go into over current shutdown to prevent damage of CPU.
