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 under 30 ns. These devices 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. Other compatible drivers are the TC4426A/TC4427A/ TC4428A family of devices. The TC4426A/TC4427A/ TC4428A devices have matched leading and falling edge input-to-output delay times, in addition to the matched rise and fall times of the TC4426/TC4427/ TC4428 devices. • Switch Mode Power Supplies • Line Drivers • Pulse Transformer Drive Package Types 8-Pin MSOP/ PDIP/SOIC TC4426 TC4427 TC4428 NC IN A GND IN B 1 8 NC 2 TC4426 7 OUT A 3 TC4427 6 VDD 4 TC4428 5 OUT B NC OUT A VDD OUT B NC OUT A VDD OUT B 8-Pin DFN-S* TC4426 TC4427 TC4428 NC 1 IN A 2 GND 3 IN B 4 EP 9 8 NC NC NC 7 OUT A OUT A OUT A 6 5 VDD VDD VDD OUT B OUT B OUT B * Includes Exposed Thermal Pad (EP); see Table 3-1.  2006-2014 Microchip Technology Inc.

Inputs A and B MOSFET driver inputs A and B are high-impedance, TTL/CMOS compatible inputs. These inputs also have 300 mV of hysteresis between the high and low thresholds that prevents output glitching even when the rise and fall time of the input signal is very slow. 3.2 Supply Input (VDD) The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 18V with respect to the Ground pin. The VDD input should be bypassed with local ceramic capacitors. The value of these capacitors should be chosen based on the capacitive load that is being driven. A value of 1.0 µF is suggested. Ground (GND) Ground is the device return pin. The Ground pin(s) should have a low-impedance connection to the bias supply source return. High peak current flows out the Ground pin(s) when the capacitive load is being discharged. 3.3 3.4 3.5 Exposed Metal Pad The exposed metal pad of the 6x5 DFN-S package is not internally connected to any potential. Therefore, this pad can be connected to a ground plane or other copper plane on a Printed Circuit Board (PCB), to aid in heat removal from the package. Output A and B MOSFET driver outputs A and B are low-impedance, CMOS push-pull style outputs. The pull-down and pullup devices are of equal strength, making the rise and fall times equivalent.  2006-2014 Microchip Technology Inc.
