TC4426/TC4427/TC4428 1.5A Dual High-Speed Power MOSFET Drivers Features: General Description: High Peak Output Current: 1.5A The TC4426/TC4427/TC4428 are improved versions of the earlier TC426/TC427/TC428 family of MOSFET Wide Input Supply Voltage Operating Range: drivers. The TC4426/TC4427/TC4428 devices have - 4.5V to 18V matched rise and fall times when charging and High Capacitive Load Drive Capability: 1000 pF in discharging the gate of a MOSFET. 25 ns (typical) These devices are highly latch-up resistant under any Short Delay Times: 40 ns (typical) 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: Withstands 0.5A Reverse 2.0 kV. Current The TC4426/TC4427/TC4428 MOSFET drivers can Input Withstands Negative Inputs Up to 5V easily charge/discharge 1000 pF gate capacitances in Electrostatic Discharge (ESD) Protected: 2.0 kV under 30ns. These devices provide low enough Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN-S impedances in both the On and Off states to ensure the Packages MOSFETs intended state is not affected, even by large transients. Applications: Other compatible drivers are the TC4426A/TC4427A/ TC4428A family of devices. The TC4426A/TC4427A/ Switch Mode Power Supplies TC4428A devices have matched leading and falling Line Drivers edge input-to-output delay times, in addition to the Pulse Transformer Drive matched rise and fall times of the TC4426/TC4427/ TC4428 devices.
