Dual High Speed Low-Side www.DataSheet4U.com MOSFET Driver POWER MANAGEMENT Description The SC1302A/B/C/D/E/F family are low cost dual lowside 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 noninverting, SC1302B is a dual inverting and SC1302C is a one inverting plus one non-inverting outp.

Dual High Speed Low-Side www.DataSheet4U.com MOSFET Driver POWER MANAGEMENT Description The SC1302A/B/C/D/E/F family are low cost dual lowside 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 noninverting, 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. SC1302A/B/C/D/E/F Features ‹ +4.5V to +16.5V operation ‹ Fast rise and fall times (20ns typical with 1000pf load) ‹ Dual MOSFET driver ‹ 2A peak drive current ‹ 40ns propagation delay ‹ 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 Applications ‹ Switch-mode power supplies ‹ Battery powered applications ‹ Solenoid and motor drives Typical Application Circuit +12V V lo a d 10uF 0 .1 u F Load A S C1302A 6 VCC IN A O U TA 1 8 EN S H D N O U TB IN B GND 3 5 7 Load B In p u tA 2 In p u tB 4 Revision: June 11, 2008 1 www.semtech.com SC1302A/B/C/D/E/F POWER MANAGEMENT Absolute Maximum Ratings www.DataSheet4U.com PRELIMINARY Exceeding the specifications below may result in permanent damage to the device, or device malfunction.
