General Description
The TC4423A/TC4424A/TC4425A devices are a family of dual-output 3A buffers/MOSFET drivers. These devices are improved versions of the earlier TC4423/TC4424/TC4425 dual-output 3A driver family. This improved version featureshigher peak output current drive capability, lower shoot-throught current, matched rise/fall times and propagation delay times.
FEATUREs
• High Peak Output Current: 4.5A (typical)
• Wide Input Supply Voltage Operating Range:
- 4.5V to 18V
• High Capacitive Load Drive Capability:
- 1800 pF in 12 ns
• Short Delay Times: 40 ns (typical)
• Matched Rise/Fall Times
• Low Supply Current:
- With Logic ‘1’ Input – 1.0 mA (maximum)
- With Logic ‘0’ Input – 150 µA (maximum)
• Low Output Impedance: 2.5Ω(typical)
• Latch-Up Protected: Will Withstand 1.5A Reverse Current
• Logic Input Will Withstand Negative Swing Up To 5V
• Pin compatible with the TC4423/TC4424/TC4425 and TC4426A/TC4427A/TC4428A devices
• Space-saving 8-Pin 150 mil body SOIC and 8-Pin 6x5 DFN Packages
APPLICATIONs
• Switch Mode Power Supplies
• Pulse Transformer Drive
