DESCRIPTION

•

Inverting and Non-Inverting Input

The UCC2753x family of devices are single-channel,

Configurations

high-speed, gate drivers capable of effectively driving

•

Enable with Fixed TTL Compatible Threshold

MOSFET and IGBT power switches by up to 2.5-A

source and 5-A sink (asymmetrical drive) peak

•

High 2.5-A Source and 2.5-A or 5-A Sink Peak

current. 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

Fast Propagation Delays (17-ns typical)

rates.

•

Fast Rise and Fall Times

The

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.

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.
