Technical Details & Description

Dual low-side driver with 1.2 A peak gate drive

The Microchip TC1426COA713 is a dual low-side MOSFET driver delivering 1.2 A peak source and 1.2 A peak sink current from a 4.5 V to 16 V supply rail. It drives both N-channel and P-channel MOSFETs with independent inverting inputs, making it a straightforward fit for low-side switching in SMPS, motor-drive pre-drive, and DC-DC converter stages where the load returns to ground.

Switching speed and logic thresholds

Typical rise time is 35 ns and fall time 25 ns into a 1 nF load, which translates to clean gate transitions at switching frequencies up to several hundred kilohertz. The logic input thresholds are 0.8 V (VIL) and 3 V (VIH), compatible with 3.3 V and 5 V logic families without external level shifting.

Housed in an 8-SOIC (0.154-inch width) package for surface-mount assembly.

Frequently asked questions

Can TC1426COA713 drive both N-channel and P-channel MOSFETs?

Yes, the TC1426COA713 is specified for both N-channel and P-channel MOSFET gate types. The inverting input logic allows direct drive of either polarity in low-side configuration.

What is the closest functional equivalent to TC1426COA713?

The MIC4427YMM is a functional peer with a 1.5 A peak output (vs 1.2 A) and non-inverting input (vs inverting). It operates over a wider -40°C to 150°C junction temperature range. The pinout and low-side configuration are similar, but the input polarity differs — verify logic compatibility before substitution.

Can I use TC1426COA713 for motor driver applications?

The TC1426COA713 is a low-side driver rated for 1.2 A peak output. It can drive the low-side MOSFETs in a motor-drive pre-drive stage, but it does not include half-bridge or high-side drive capability. For a full H-bridge or three-phase motor drive, pair it with a high-side driver or use a dedicated half-bridge driver such as the MIC4104YM.
