SLVSC82B August 2013 – October 2015 UCC27531-Q1
PRODUCTION DATA.
The driver has the EN pin with fixed TTL compatible threshold. The EN pin is internally pulled up; pulling the EN pin low disables driver, while leaving it open provides normal operation. The EN pin can be used as an additional input with the same performance as the IN pin.
Leaving the input pin of driver open holds the output low. The logic behavior of the driver is shown in the application diagram, timing diagram and input and output logic truth table.
Internal circuitry on the VDD pin provides an UVLO function that holds output low until VDD supply voltage is within operating range.
The UCC27531-Q1 driver is offered in a 6-pin standard SOT-23 (DBV) package. The device operates over wide temperature range of –40°C to 140°C.
