TC4426AM/TC4427AM/TC4428AM 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 (typ.) • Short Delay Times: 30 ns (typ.) • Matched Rise, Fall and Delay Times • Low Supply Current: - With Logic ‘1’ Input – 1 mA (typ.) - With Logic ‘0’ Input – 100 µA (typ.) • Low Output Impedance: 7(typ.) • 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 TC426M/TC427M/TC428M and TC4426M/TC4427M/TC4428M • Wide Operating Temperature Range: - -55°C to +125°C • See TC4426A/TC4427A/TC4428A Data Sheet (DS21423) for additional temperature range and packaging offerings The TC4426AM/TC4427AM/TC4428AM are improved versions of the earlier TC4426M/TC4427M/TC4428M family of MOSFET drivers. In addition to matched rise and fall times, the TC4426AM/TC4427AM/TC4428AM devices have matched leading and falling edge propagation delay times. 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 4 kV. The TC4426AM/TC4427AM/TC4428AM MOSFET drivers can easily charge/discharge 1000 pF gate capacitances in under 30 ns, while providing low enough impedances in both the on and off states to ensure the MOSFET's intended state will not be affected, even by large transients.

TABLE 3-1: PIN FUNCTION TABLE 8-Pin Symbol CERDIP 3.1 3.3 Outputs A & B (OUT A and OUT B) MOSFET driver OUT A & 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. Description 3.4 1 NC No connection 2 IN A Input A 3 GND Ground 4 IN B Input B 5 OUT B 6 VDD 7 OUT A 8 NC Output B Supply input 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. Output A No connection Inputs A & B (IN A and IN B) MOSFET driver IN A & B are high-impedance, TTL/CMOS-compatible inputs. These inputs also have 300 mV of hysteresis between the high and low thresholds, which prevents output glitching even when the rise and fall time of the input signal is very slow. 3.2 Ground (GND) The GND pin is the return path for both the bias current and the high peak current that discharges the external load capacitance. The ground pin should be tied into a ground plane or have a very short trace to the bias supply source return. 2005-2013 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
