Description

The ISL6614CRZ belongs to ISL6614, which integrates two ISL6613 MOSFET drivers and is sipecifically designed to drive two independent power channels in a Multi-Phase interleaved buck converter topology. These drivers combined with HlP63xx or lSL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs form complete core-voltage regulator solutions for advanced microprocessors. The ISL6614CRZ drives both the upper and lower gates simultaneously over a range from 5V to 12v. This drive- voltage ISL6614CRZ provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. An advanced adaptive zero shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize the dead time. These products ISL6614CRZ add an overvoltage protection feature operational before VCC exceeds its turn-on threshold, at which the PHASE node is connected to the gate of the low side MOSFET (LGATE). The output voltage of the converter is then limited by the threshold of the low side MOSFET which provides some protection to the microprocessor if the upper MOSFET(s) is shorted during stanup. The over- temperature protection feature prevents failures resulting from excessive power dissipation by shutting off the outputs when itsjunction temperature exceeds 150"C (typically). The driver resets once its junction temperature returns to 108 (typically). The ISL6614CRZ also features a three-state PWM input which, working together with IntersiI's multi-phase PWM controllers, prevents a negative transient on the output voltage when the output is shut down. This feature eliminates the Schottky diode that is used in some systems for protecting the load from reversed output voltage events.

The features of ISL6614CRZ can be summarized as (1)pin-to-pin compatible with HIP6602 SOIC family for better; (2)perfomrance and extra protection features ; (3)quad N-channel MOSFET drives for two synchronous rectified bridges ; (4)advanced adaptive zero shoot-through protection: body diode detection; auto-zero of rDS(ON) conduction offset effect ; (5)adjustable gate voltage(5V to 12V) for optimal efficiency ; (6)internal bootatrap schottky diode; (7)bootstrap capacitor overcharging prevention ; (8)supports high switching frequency (up to 1MHz):3A sinking current capability; fast rise/fall times and low propagation delays; (9)three-state PWM input for output stage shutdown ; (10)Three-state PWM input hysteresis for applications with ; (11)power sequencing requirement ; (12)Pre-POP overvoltage +protection ; (13)VCC undervoltage protection ; (14)over temperature protection (OTP) with 42 hysteresis ; (15)expandable bottom copper pad for enhanced heat sinking ; (16)QFN Package:compliant to JEDEC PUB95 MO 220 QFN - Quad flat no leads - package outline; near chip scale package footprint, which improves PCB etticiency and has a thinner profile ; (17)Pb-Free plus anneal available (ROHS compliant).
