General Description:

The TC4426A/TC4427A/TC4428A are improvedversions of the earlier TC4426/TC4427/TC4428 familyof MOSFET drivers. In addition to matched rise and falltimes, the TC4426A/TC4427A/TC4428A devices havematched leading and falling edge propagation delaytimes.

These devices are highly latch-up resistant under anyconditions within their power and voltage ratings. Theyare not subject to damage when up to 5V of noisespiking (of either polarity) occurs on the ground pin.

They can accept, without damage or logic upset, up to500 mA of reverse current (of either polarity) beingforced back into their outputs. All terminals are fullyprotected against Electrostatic Discharge (ESD) up to4 kV.

The TC4426A/TC4427A/TC4428A MOSFET driverscan easily charge/discharge 1000 pF gatecapacitances in under 30 ns. These devices providelow enough impedances in both the on and off states toensure the MOSFET’s intended state will not beaffected, even by large transients.


Features:

• High Peak Output Current – 1.5A

• Wide Input Supply Voltage Operating Range: - 4.5V to 18V

• High Capacitive Load Drive Capability – 1000 pF in 25 ns (typ.)

• Short Delay Times – 30 ns (typ.)

• Matched Rise, Fall and Delay Times

• Low Supply Current: - With Logic ‘1’ Input – 1 mA (typ.) - With Logic ‘0’ Input – 100 μA (typ.)

• Low Output Impedance – 7Ω (typ.)

• Latch-Up Protected: Will Withstand 0.5A Reverse Current

• Input Will Withstand Negative Inputs Up to 5V

• ESD Protected – 4 kV

• Pin-compatible with TC426/TC427/TC428 and TC4426/TC4427/TC4428

• Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN Packages Applications:

• Switch Mode Power Supplies • Line Drivers • Pulse Transformer Drive
