SC1301A Datasheet, PDF (1/9 Pages) Semtech Corporation – 2A High Speed Low-Side MOSFET Driver in SOT-23

POWER MANAGEMENT
Description
The SC1301A/B is a cost effective single-channel high-
speed MOSFET driver. The driver is capable of driving a
1000pF load in 20ns rise/fall time and has a 60ns propa-
gation delay time from input transition to the gate of the
power MOSFET. The high current driving capability
(2A peak) allows fast switching up to 1MHz. The SC1301A
is noninverting and the SC1301B is inverting.
An Undervoltage lockout circuit is included to guarantee
that the driver output is low when Vcc is less than or
equal to 4.1V (typ) at supply ramp up. An internal tem-
perature sensor shuts down the driver in the event of
overtemperature. The 5-pin SOT-23 package uses mini-
mum space.
