TC4426/TC4427/TC4428
1.5A Dual High-Speed Power MOSFET Drivers
Features: General Description: 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 (typical) Short Delay Times: 40 ns (typical) Matched Rise and Fall Times Low Supply Current:
-With Logic �1’ Input – 4 mA
-With Logic �0’ Input – 400 µA Low Output Impedance: 7 Latch-Up Protected: Withstands 0.5A Reverse
Current Input Withstands Negative Inputs Up to 5V Electrostatic Discharge (ESD) Protected: 2.0 kV Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN-S
Packages 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. Applications: 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 …
