TC4428 Application Note

●General Description:

●The TC4426A/TC4427A/TC4428A are improved versions of the earlier TC4426/TC4427/TC4428 family of MOSFET drivers. In addition to matched rise and fall times, the TC4426A/TC4427A/TC4428A devices have matched leading and falling edge propagation delay

●times.

●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 – 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 – 7Ω (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 TC426/TC427/TC428 and TC4426/TC4427/TC4428

●• Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN Packages
