Detailed Description

Single-channel, low-side MOSFET gate driver

Non-inverting input, drives N-channel or P-channel MOSFET gates

Very high peak output current: 6 A source / 6 A sink

Wide supply range: 4.5 V to 18 V

Fast edges: 12 ns typical rise, 13 ns typical fall

TTL/CMOS-compatible logic thresholds (VIL 0.8 V, VIH 2.4 V)

Industrial/automotive-grade junction temperature range: -40°C to +150°C (TJ)

Small outline 8-MSOP package, RoHS3 compliant

Mounting: Surface Mount (SMD)

Key Features

Single low-side gate driver, non-inverting logic

6 A peak source and 6 A peak sink for strong gate charge control

4.5–18 V supply supports 5 V, 12 V, and intermediate rails

Fast transition times (12/13 ns typ) reduce switching losses

TTL/CMOS compatible input thresholds for easy MCU/logic drive

Operates over -40°C to +150°C junction temperature

Works with N-channel and P-channel MOSFETs on the low side

Compact 8-MSOP footprint for dense layouts

Tape & Reel packaging for automated assembly

RoHS3 compliant lead finish

Key Advantages

High peak current quickly charges/discharges large MOSFET gates, reducing turn-on/turn-off time and improving efficiency

Non-inverting input simplifies logic interface; no extra inversion stage needed

Wide supply range covers common driver rails without external regulators

Fast edges lower switching losses in high-frequency power stages

Small package saves board space while maintaining thermal performance

Broad operating temperature range suits rugged, high-ambient environments

Lifecycle

Status: Active and in ongoing production by Microchip Technology (based on latest public information). Not near end-of-life as of our most recent update.

Direct equivalents and close alternatives:

- Microchip TC4420 series (single, 6 A, non-inverting) — functional alternative; check pinout and specs

- Microchip MIC4420 in other package options (e.g., different tape, tube, or package variants) — same function; package differs

- Microchip MIC4421 (single, 6 A, inverting) — use if an inverting input is acceptable

- Microchip TC4429 (single, 6 A, inverting) — use if an inverting input is acceptable

- Texas Instruments UCC27511A/UCC27512A (single-channel, high-speed gate drivers; different peak currents/pinouts) — verify drive strength and pinout

- ON Semiconductor NCP81074A or NCP81071 (single-channel MOSFET drivers; different current and pins) — verify specs and layout impact

Important note: Always verify pinout, logic polarity, supply range, drive current, and timing before substituting. If you need a drop-in, pin-compatible alternative or guidance on second sources, please contact our sales team via the Y-IC website for personalized support.
