Dual 5A low-side gate driver for IGBTs and MOSFETs
The Texas Instruments UCC27525D is a dual-channel low-side gate driver for IGBTs and N-Channel MOSFETs. It delivers 5A peak source and sink current with 7ns typical rise time and 6ns typical fall time.
5A peak drive — what it means for switching losses
The 5A peak source and sink current charges and discharges gate capacitance. The 7ns rise and 6ns fall times confirm the driver's ability to slew the gate voltage quickly.
The 4.5V to 18V supply range means this driver can run from a 5V bias rail or a 12V/15V auxiliary supply common in industrial power stages. The logic input thresholds — 1V VIL and 2.3V VIH — are compatible with 3.3V and 5V logic families without external level shifting. This simplifies the interface from a PWM controller or microcontroller. The 8-SOIC package is a standard footprint, and the surface-mount mounting suits automated assembly.
The active status means it remains suitable for new designs without near-term obsolescence risk.
