DESCRIPTION
Inverting and Non-Inverting Input
Configurations
The UCC2753x family of devices are single-channel,
high-speed, gate drivers capable of effectively driving
MOSFET and IGBT power switches by up to 2.5-A
source and 5-A sink (asymmetrical drive) peak
current. Strong sink capability in asymmetrical drive
boosts immunity against parasitic Miller turn-on effect.
The UCC2753x device can also feature a split-output
configuration where the gate-drive current is sourced
through OUTH pin and sunk through OUTL pin. This
pin arrangement allows the user to apply independent
turn-on and turn-off resistors to the OUTH and OUTL
pins respectively and easily control the switching slew
rates.
•
•
Enable with Fixed TTL Compatible Threshold
High 2.5-A Source and 2.5-A or 5-A Sink Peak
Drive Currents at 18-V VDD
•
•
Wide VDD Range From 10 V up to 35 V
Input and Enable Pins Capable of
Withstanding up to -5-V DC Below Ground
•
Output Held Low When Inputs are Floating or
During VDD UVLO
•
•
Fast Propagation Delays (17-ns typical)
Fast Rise and Fall Times
(15-ns and 7-ns typical with 1800-pF Load)
The driver has rail-to-rail drive capability and
extremely small propagation delay typically 17 ns.
•
•
Under Voltage Lockout (UVLO)
The input threshold of UCC2753xDBV is based on
TTL and CMOS compatible low-voltage logic, which
is fixed and independent of VDD supply voltage. The
1-V typical hysteresis offers excellent noise immunity.
Used as a High-Side or Low-Side Driver (if
designed with proper bias and signal isolation)
•
•
•
Low Cost, Space Saving 5-Pin or 6-Pin DBV
(SOT-23) Package Options
The driver has EN pin with fixed TTL compatible
threshold. EN is internally pulled up; pulling EN 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, IN+, IN1,
and IN2 pins.
UCC27536 and UCC27537 Pin-to-Pin
compatible to TPS2828 and TPS2829
Operating Temperature Range of -40°C to
140°C
