Dual High Speed Low-Side
MOSFET Driver
POWER MANAGEMENT
Description
The SC1302A/B/C/D/E/F family are low cost dual low-
side MOSFET drivers. These drivers accept TTL-compat-
ible inputs and are capable of supplying high current
outputs (> 2A peak) to external MOSFETs. Fast switch-
ing allows operation up to 1 MHz. The SC1302A/B/C is
available in six configurations: SC1302A is a dual non-
inverting, SC1302B is a dual inverting and SC1302C is a
one inverting plus one non-inverting output.
The SC1302D/E/F is the derivative part from SC1302A/
B/C with pin 1 (EN) and pin 8 (SHDN) internally tied to
VCC.
An under-voltage lockout circuit guarantees that the
driver outputs are low when Vcc is less than 4.5V (typ).
An internal temperature sensor shuts down the driver in
the event of over temperature.
