SiP32430 www.vishay.com Vishay Siliconix 28 V, 99 m , Load Switch with Programmable Current Limit and Slew Rate Control OPERATION DESCRIPTION FEATURES The SiP32430 is a load switch integrates multiple control 6 V to 28 V operation features that simplify the design and increase the reliability Programmable soft start of the circuitry connected to the switch. The SiP32430 is Programmable current limit designed to operate in the 6 V to 28 V range. Over temperature protection An internally generated gate drive voltage ensures low On resistance 99 m Available switch resistance over the wind input voltage operating range. Power good, when V reaches 90 % of V OUT IN The SiP32430 has a slew rate control circuit that programs OCP / OTP fault flag the switch turn-on time to the value set by an external Under voltage lockout: 4.8 V / 5.4 V (typ. / max.) capacitor. If no OTP, auto re-try to soft turn on 150 ms after the An over-current protection circuit (OCP) continuously switch protected off monitors the current through the load switch. When the over Package: DFN10 3 mm x 3 mm current protection is triggered, the circuit controls the switch Material categorization: for definitions of compliance impedance to clamp the current to the level programmed by please see www.vishay.com/doc 99912 an external resistor. The trigger current is typically 8 % over the set current limit. In case the over-current condition APPLICATIONS persists for more than 7 ms, the switch shuts off automatically. Personal computers The SiP32430 has an over temperature protection circuit Lighting (OTP) which will shut the switch off immediately if th e Flat panel displays junction temperature exceeds over temperature limit of Game consoles typically 150 C. The OTP circuit will release the switch when the temperature has decreased by about 20 C of Industrial hysteresis. Network communication When an OCP or an OTP fault condition is detected the FLG Data storage pin is pulled low. The fault flag will release 150 ms after the fault condition is cleared, and the switch will automatically turn on at the programmed slew rate. The SiP32430 features a low voltage control logic interfac e which can be controlled without the need for level shifting. It also includes a power good flag. The SiP32430 is available in a space efficient DFN10 of 3 mm x 3 mm package. TYPICAL APPLICATION CIRCUIT Fig. 1 - SiP32430 Typical Application Circuit S20-0528-Rev.
