UCC27532 Overview
Description
The UCC27532 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.
Key Features
- Low Cost Gate Driver (offering optimal solution for driving FET and IGBTs)
- Superior Replacement to Discrete Transistor Pair Drive (providing easy interface with controller)
- CMOS Compatible Input Logic Threshold (becomes fixed at VDD above 18 V)
- 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
- Wide VDD Range From 10 V up to 35 V
- Input 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)
