Strong sink capability in asymmetrical drive Drive Currents at 18-V VDD boosts immunity against parasitic Miller turn-on effect. • Wide VDD Range From 10 V up to 35 V The UCC2753x device can also feature a split-output • Input and Enable Pins Capable of configuration where the gate-drive current is sourced Withstanding up to -5-V DC Below Ground through OUTH pin and sunk through OUTL pin. This pin arrangement allows the user to apply independent • Output Held Low When Inputs are Floating or turn-on and turn-off resistors to the OUTH and OUTL During VDD UVLO pins respectively and easily control the switching slew • Fast Propagation Delays (17-ns typical) rates. • Fast Rise and Fall Times The driver has rail-to-rail drive capability and (15-ns and 7-ns typical with 1800-pF Load) extremely small propagation delay typically 17 ns. • Under Voltage Lockout (UVLO) The input threshold of UCC2753xDBV is based on • Used as a High-Side or Low-Side Driver (if TTL and CMOS compatible low-voltage logic, which designed with proper bias and signal isolation) is fixed and independent of VDD supply voltage. The • Low Cost, Space Saving 5-Pin or 6-Pin DBV 1-V typical hysteresis offers excellent noise immunity. (SOT-23) Package Options The driver has EN pin with fixed TTL compatible • UCC27536 and UCC27537 Pin-to-Pin threshold. EN is internally pulled up; pulling EN low compatible to TPS2828 and TPS2829 disables driver, while leaving it open provides normal operation. The EN pin can be used as an additional • Operating Temperature Range of -40°C to input with the same performance as the IN, IN+, IN1, 140°C and IN2 pins.
