4 This is just an example, we prefer to use the TC4422 in the T0-220 package which has higher Current capability but is single channel. You can order free samples from microchip

5 Components: TC4421/TC4422 Features High Peak Output Current: 9A Wide Input Supply Voltage Operating Range: 4.5V to 18V High Continuous Output Current: 2A Max Fast Rise and Fall Times:  30 ns with 4,700 pF Load  180 ns with 47,000 pF Load Short Propagation Delays: 30 ns (typ) Low Supply Current:  With Logic ‘1’ Input: 200 µA (typ)  With Logic ‘0’ Input: 55 µA (typ) Low Output Impedance: 1.4 (typ) Latch-Up Protected: Will Withstand 1.5A Output Reverse Current Input Will Withstand Negative Inputs Up To 5V Pin-Compatible with the TC4420/TC4429 6A MOSFET Driver Space-saving 8-Pin 6x5 DFN Package =en010665
