Product details

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.

Frequently asked questions

Is UCC27525D suitable for driving high-power IGBTs?

Yes, the UCC27525D is specified for IGBT and N-Channel MOSFET gates. With 5A peak source/sink current and 7ns/6ns rise/fall times, it can drive medium-to-high-power IGBT modules in hard-switched converters, provided the total gate charge and switching frequency stay within the driver's power dissipation limits. For very large modules (> 1 µC gate charge), consider an external booster stage or a higher-current driver.

Can UCC27525D be used as a low-side driver in a half-bridge configuration?

Yes, the UCC27525D is a dual low-side driver with independent channels. In a half-bridge, each channel can drive one low-side switch. For the high-side switch you would need a separate bootstrap or isolated supply and a high-side driver — this part alone does not provide level-shifted high-side drive.
