SC1302A/B/C/D/E/F
Dual High Speed Low-Side
MOSFET Driver
Description
The SC1302A/B/C/D/E/F family are low cost dual low-side
MOSFET drivers. These drivers accept TTL-compatible
inputs and are capable of supplying high current outputs
(> 2A peak) to external MOSFETs. Fast switching 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 alone has an 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 (typical).
An internal temperature sensor shuts down the driver in
the event of over temperature.
