COS27423, COS27424, COS27425 4.5A Dual High-Speed Power MOSFET Drivers with Enable
●The COS27423/4/5 are matched dual power MOSFET drivers. Unique circuit design enables high speed operation capable of delivering peak currents of 4.5A into 1800pF capacitive loads. Improved speed and drive capability are enhanced by matched rise and fall delay times. These matched delays maintain the integrity of input-to-output pulse-widths to reduce timing errors and clock skew problems. Dynamic switching losses are minimized with non-overlapped drive techniques. 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 COS27423/4/5 inputs can be driven directly from either TTL or CMOS (1.8V to 25V). In addition, the 300mV of built-in hysteresis provides noise immunity and allows the device to be driven from slow rising or falling waveforms. The COS27423/4/5 provides enable functions (EN) to control the operation of the driver applications. ENA and ENB are implemented on pins1 and 8 which were previously left unused in the industry standard pin-out. They are internally pulled up to VDD for active high logic and can be left open for standard operation.
