3 / 16 page 3 FN9005.4 June 10, 2005 2 GATE_A FET Gate Drive Output ISL6125 Open Drain Outputs Drives the external FETs with a 1µA current source to soft start ramp into the load. On the ISL6125 only, these are open drain outputs that can be pulled up to a maximum of VDD voltage. 5GATE_B 6GATE_C 7GATE_D 22 SYSRST# System Reset I/O As an input, allows for immediate and unconditional latch-off of all GATE outputs when driven low. This input can also be used to initiate the programmed sequence with ‘zero’ wait (no 10ms stabilization delay) from input signal on this pin being driven high to first GATE. As an output when there is a UV condition this pin pull low. If common to other SYSRST# pins in a multiple IC configuration it will cause immediate and unconditional latch-off of all other GATEs on all other ISL612X sequencers. This pin is a NC on ISL6126 and ISL6128 19 No Connect No Connect No Connect ISL612X Variant Feature Matrix PART NAME EN/EN# CMOS/ TTL GATE DRIVE OR OPEN DRAIN OUTPUTS REQUIRED CONDITIONS FOR INITIAL START-UP NUMBER OF UVLO INPUTS MONITORED BY EACH RESET# NUMBER OF CHANNELS THAT TURN-OFF WHEN 1 UVLO FAULTS PRESET OR ADJUSTABLE SEQUENCE NUMBER OF UVLO AND PAIRS OF I/O FEATURES ISL6123 EN TTL Gate Drive 4 UVLO 1 EN 4 UVLO 4 Gates Adjustable On & Off 4 Monitors with 1 I/O Auto restart ISL6124 EN# CMOS Gate Drive 4UVLO 1 EN 4 UVLO 4 Gates Adjustable On & Off 4 Monitors with 1 I/O Auto restart ISL6125 EN# CMO Open Drain 4 UVLO 1 EN 4 UVLO 4 Open Drain Adjustable On & Off 4 Monitors with 1 I/O Auto restart ISL6126 EN# CMOS Gate Drive 1 UVLO 1 EN 4 UVLO 1 Gate Adjustable Off 4 Monitors with 1 I/O Gates independent on as UVLO Valid ISL6127 EN# CMOS Gate Drive 4 UVLO 1 EN 4 UVLO 4 Gates Preset 4 Monitors with 1 I/O Auto restart ISL6128 EN# CMOS Gate Drive 4 UVLO 2 EN 2 UVLO 2 Gates Preset 2 Monitors with 2 I/O Dual Redundant Operation Pin Descriptions (Continued) PIN # PIN NAME FUNCTION DESCRIPTION ISL6123, ISL6124, ISL6125, ISL6126, ISL6127, ISL6128 |
