SC1302A_09

SC1302A/B/C/D/E/F Dual High Speed Low-Side MOSFET Driver POWER MANAGEMENT Features Operating Voltage — +4.5V to +16.5V Fast rise and fall times (20ns typical with 1000pf load) Dual MOSFET driver Peak drive current — 2A propagation delay — 40ns 8-pin SOIC / MSOP lead free packages. This product is fully WEEE and RoHS compliant Enable/disable control TTL-compatible input Under voltage lockout with hysteresis Low shutdown supply current Over temperature protection ESD protection Dual inverting/non-inverting and inverting/non-inverting configurations 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.
