TC4426M/TC4427M/TC4428M 1.5A Dual High-Speed Power MOSFET Drivers Features General Description High Peak Output Current 1.5A The TC4426M/TC4427M/TC4428M are improved versions of the earlier TC426M/TC427M/TC428M Wide Input Supply Voltage Operating Range: family of MOSFET drivers. The TC4426M/TC4427M/ - 4.5V to 18V TC4428M devices have matched rise and fall times High Capacitive Load Drive Capability 1000 pF when charging and discharging the gate of a MOSFET. in 25 ns (typ.) These devices are highly latch-up resistant under any Short Delay Times 40 ns (typ.) conditions within their power and voltage ratings. They Matched Rise and Fall Times are not subject to damage when up to 5V of noise Low Supply Current: spiking (of either polarity) occurs on the ground pin. - With Logic 1 Input 4 mA They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being - With Logic 0 Input 400 A forced back into their outputs. All terminals are fully Low Output Impedance 7 protected against Electrostatic Discharge (ESD) up to Latch-Up Protected: Will Withstand 0.5A Reverse 4kV. Current The TC4426M/TC4427M/TC4428M MOSFET drivers Input: Will Withstand Negative Inputs Up to 5V can easily charge/discharge 1000pF gate ESD Protected 4 kV capacitances in under 30 ns and provide low enough Pin-Compatible with the TC426M/TC427M/ impedances in both the on and off states to ensure the TC428M, TC4426AM/TC4427AM/TC4428AM MOSFET s intended state will not be affected, even by Devices large transients. Wide Operating Temperature Range: The TC4426AM/TC4427AM/TC4428AM family of - -55C to +125C devices are also compatible drivers. The TC4426AM/ See TC4426/TC4427/TC4428 data sheet TC4427AM/TC4428AM devices have matched (DS21422) for additional temperature range and leading and falling edge input-to-output delay times, in packaging offerings addition to the matched rise and fall times of the TC4426M/TC4427M/TC4428M devices.
