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.
