TC4426EOA713 Specification:

TC4426 TC4427 TC4428 Microchip 1.5A Dual High-Speed Power MOSFET Drivers IC General Description:

The TC4426/TC4427/TC4428 are improved versions of the earlier TC426/TC427/TC428 family of MOSFET drivers.

The TC4426/TC4427/TC4428 devices have matched rise and fall times when charging and discharging the gate of a MOSFET. These devices are highly latch-up resistant under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against Electrostatic Discharge (ESD) up to 2.0 kV.

The TC4426/TC4427/TC4428 MOSFET drivers can easily charge/discharge 1000 pF gate capacitances in under 30 ns. These devices provide low enough impedances in both the On and Off states to ensure the MOSFET’s intended state is not affected, even by large transients. Other compatible drivers are the TC4426A/TC4427A/ TC4428A family of devices.

The TC4426A/TC4427A/ TC4428A devices have matched leading and falling edge input-to-output delay times, in addition to the matched rise and fall times of the TC4426/TC4427/ TC4428 devices.
