SLUSBA7A – DECEMBER 2012  
2.5-A and 5-A, 35-VMAX VDD FET and IGBT Single-Gate Driver  
Check for Samples: UCC27531

FEATURES  
DESCRIPTION  
•
Low Cost Gate Driver (offering optimal  
solution for driving FET and IGBTs)  
The UCC27531 is a single-channel, high-speed, gate  
driver 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 UCC27531  
•
Superior Replacement to Discrete Transistor  
Pair Drive (providing easy interface with  
controller)  
•
•
TTL and CMOS Compatible Input Logic  
Threshold, (independent of supply voltage)  
device also features  
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.  
Split Outputs Allow Separate Turn-On and  
Turn-Off Tuning  
•
•
Enable with Fixed TTL Compatible Threshold  
High 2.5-A Source and 5-A Sink Peak Drive  
Currents at 18-V VDD  
The driver has rail-to-rail drive capability and  
extremely small propagation delay typically 17 ns.  
•
•
Wide VDD Range From 10 V up to 35 V  
Input Pins Capable of Withstanding up to -5-V  
DC Below Ground  
The input threshold of UCC27531DBV 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.  
•
Output Held Low When Inputs are Floating or  
During VDD UVLO  
•
•
Fast Propagation Delays (17-ns typical)  
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 pin.  
Fast Rise and Fall Times  
(15-ns and 7-ns typical with 1800-pF Load)  
•
•
Under Voltage Lockout (UVLO)  
Used as a High-Side or Low-Side Driver (if  
designed with proper bias and signal isolation)  
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.  
•
•
Low Cost, Space Saving 6-Pin DBV (SOT-23)  
Package  
Operating Temperature Range of -40°C to  
140°C  
Internal circuitry on VDD pin provides an under  
voltage lockout function that holds output low until  
VDD supply voltage is within operating range.

Switch-Mode Power Supplies  
DC-to-DC Converters  
The UCC27531 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.
