COS4420/4429 6A High-Speed Power MOSFET Drivers
●The COS4420/4429 are single-output power MOSFET drivers. Unique circuit design enables high speed operation capable of delivering peak currents of 6A into 10,000pF capacitive loads. Improved speed and drive capability are enhanced by matched rise and fall delay times. Dynamic switching losses are minimized with non-overlapped drive techni-ques. These devices are highly latch-up resistant 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.
●The COS4420/4429 inputs can be driven directly from either TTL or CMOS (1.6V to 25V). In addition, the 300 mV of built-in hysteresis provides noise immunity and allows the device to be driven from slow rising or falling waveforms. Output is held LOW if Input is unbiased or floating.
■Features:
●High Peak Output Current: 6A
●Wide Supply Voltage Operating Range: 4.5V to 25V
●High Capacitive Load Drive Capability 10 nF
●Short Delay Times: 44ns (typ.)
●Matched Rise/Fall Times (14ns typ.)
●Low Output Impedance：1.0Ω (typ.)
●Low Supply Current
●Over-temperature Protection
●Under-voltage Lockout (UVLO)
●Non-overlapped Drive Tech
●Input withstands negative inputs up to 5V
●Available in Green SOP8, DIP8 and DFN8 Packages
