Low-Side Gate Drivers

The EG Micro EG44273 is a single-channel, high-speed low-side gate driver IC designed to drive MOSFET and IGBT power switches with fast, rail-to-rail output capability and an ultra-low quiescent current, making it ideal for both high-frequency switching converters and battery-powered applications. Operating from a wide supply range of 4V to 20V, it delivers a symmetric 2A peak source (I_OH) and 2A peak sink (I_OL) output at V_CC = 12V, with a fall time (T_F) of just 20ns for fast, clean turn-off. A standout feature is the exceptionally low quiescent current of below 1µA, minimising no-load power draw in energy-sensitive designs. The output is held low when the input pin is floating, ensuring safe default behaviour. ABL Semi supplies the EG44273 as a 100% authentic EG Micro product in SOT-23-5, with flexible MOQ as a pin-to-pin alternative to the TI UCC27517 and similar low-side drivers.

The Slkor SL27517 is a single-channel, low-side MOSFET and IGBT gate driver IC featuring a dual-input design configurable for either non-inverting or inverting operation, making it exceptionally flexible for PWM control, enable/disable, and logic inversion applications in switching power converters. Operating from a wide supply range of 4.5V to 20V (rated up to 24V), the SL27517 delivers a fast and symmetric 4A peak source (I_OH) and 4A peak sink (I_OL) output current with industry-leading rise and fall times of just 6ns each — among the fastest in the SOT-23-5 gate driver class. Negative input capability down to -5V, TTL/CMOS logic compatibility, output-low failsafe on floating input, and a propagation delay typically below 20ns complete a compelling feature set. ABL Semi supplies the SL27517 as a 100% authentic Slkor product in SOT-23-5, with flexible MOQ and direct pin-to-pin compatibility to the TI UCC27517 and equivalent low-side gate drivers.

The UMW UCC27517DBVR is a single-channel, low-side in-phase gate driver IC for power MOSFETs and IGBTs, built on proprietary latch-immune CMOS technology for high robustness in demanding switching power applications. Operating from a wide supply range of 5V to 25V, it delivers a symmetrical 4A source (I_OH) and 4A sink (I_OL) peak output current with fast matched rise and fall times of just 10ns each, enabling precise, low-loss gate switching at high frequencies. The logic input is compatible with CMOS, TTL, and 3.3V signal levels, and integrated UVLO with hysteresis prevents under-driven gate conditions during supply ramp events. The device operates across a wide temperature range of -40°C to 125°C. ABL Semi supplies the UCC27517DBVR as a 100% authentic UMW product in the compact SOT-23-5 package, with flexible MOQ as a direct pin-to-pin alternative to the TI UCC27517.
