... Indicator 6, 7 OUT_2, 1 Channel 2,1 Controlled Supply Output 3 ISL6119 DESCRIPTION VIN provides chip bias voltage. At VIN < 2.5V chip functionality is disabled, FAULT latch is cleared and floating and OUT is held low. Enables / Disables switch. Channel overcurrent fault indicator. FAULT floats and is disabled until VIN >2.5V. This output is pulled low after the OC timeout period has expired and stays latched until ENABLE is deasserted ...
