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. 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 – 40 ns (typ.) • Matched Rise and Fall Times • Low Supply Current: \- With Logic ‘1’ Input – 4 mA \- With Logic ‘0’ Input – 400 μA • Low Output Impedance – 7Ω • Latch-Up Protected: Will Withstand 0.5A Reverse Current • Input Will Withstand Negative Inputs Up to 5V • ESD Protected – 4 kV • Pin-compatible with the TC426/TC427/TC428 • Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN Packages
The TC4426EOA is a dual inverting high-speed Power MOSFET Driver for pulse transformer drive. The TC4426 device have matched rise and fall times when charging and discharging the gate of a MOSFET. This device is highly latch-up resistant under any conditions within their power and voltage ratings. It is not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. It can accept, without damage or logic upset, up to 500mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against Electrostatic Discharge (ESD) up to 2.0kV. The TC4426 MOSFET driver can easily charge/discharge 1000pF gate capacitances in under 30ns. This device 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.
