VDD Fet and IGBT Single-Gate Driver
1
Features
Qualified for automotive applications
AEC-Q100 qualified with the following results:
Device temperature grade 1
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 18V)
Split outputs allow separate turnon and turnoff tuning
Enable with Fixed TTL compatible threshold
High 2.5A source and 5A sink peak-drive currents at 18V VDD
Wide VDD range from 10V up to 35V
Input pins capable of withstanding up to –5V DC below ground
Output held low when inputs are floating or during VDD UVLO
Fast propagation delays (17ns typical)
Fast rise and fall times
(15ns and 7ns typical with 1800pF load)
Undervoltage lockout (UVLO)
Used as a high-side or low-side driver (if designed with proper bias and signal isolation)
Low-cost space-saving 6-pin DBV (SOT-23) package
Operating temperature range of –40°C to 140°C
