SC1301A/B 2A High Speed Low-Side MOSFET Driver in SOT-23 POWER MANAGEMENT Description Features The SC1301A/B is a cost effective single-channel high- +4.5V to +16.5V operation speed MOSFET driver. The driver is capable of driving a Fast rise and fall times 1000pF load in 20ns rise/fall time and has a 60ns propa- (20ns typical with 1000pf load ) gation delay time from input transition to the gate of the 2A peak drive current power MOSFET. The high current driving capability Enable/disable control (2A peak) allows fast switching up to 1MHz. The SC1301A TTL-compatible input is noninverting and the SC1301B is inverting. Inverting or noninverting versions Undervoltage lockout An Undervoltage lockout circuit is included to guarantee Low supply current that the driver output is low when Vcc is less than or -40C to 85C ambient temperature operating range equal to 4.1V (typ) at supply ramp up. An internal tem- Over temperature protection perature sensor shuts down the driver in the event of overtemperature. The 5-pin SOT-23 package uses mini- ESD protection mum space. SOT-23-5 package. Also available in Lead-free, fully WEEE and RoHS compliant.
