SiP32419, SiP32429 www.vishay.com Vishay Siliconix 28 V, 56 m, Load Switch with Programmable Current Limit and Slew Rate Control OPERATION DESCRIPTION FEATURES SiP32419 and SiP32429 are load switches that integrate 6 V to 28 V operation voltage multiple control features that simplify the design and 56 m typical on resistance increase the reliability of the circuitry connected to the Programmable soft start switch. Both devices are 56 m switches designed to Programmable current limit operate in the 6 V to 28 V range. An internally generated gate drive voltage ensures good R linearity over the inpu t ON Programmable soft start control Available voltage operating range. Over temperature protection The SiP32419 and SiP32429 have a slew rate control circuit Power good, when V reaches 90 % of V OUT IN that controls the switch turn-on time to the value set by an Fault flag on for thermal shutdown and OCP external capacitor. Under voltage lockout: 4.8 V / 5.4 V (typ. / max.) After soft start, an over-current protection circuit (OCP) Auto-retry SiP32429 and latch-off SiP32419 versions continuously monitors the current through the load switch, and controls the switch impedance to limit the current to the Package: DFN-10 3 mm x 3 mm level programmed by an external resistor. If the over-current IEC 62368-1 certified condition persists for more than 7 ms, the switch shuts off Material categorization: for definitions of compliance automatically. The SiP32419 and SiP32429 has an ove r please see www.vishay.com/doc 99912 temperature protection circuit (OTP) which will shut th e switch off if the junction temperature exceeds about 135 C. APPLICATIONS The OTP circuit will release the switch when the temperatur e has decreased by about 40 C of hysteresis. eFuse, smart load switch When an OCP or an OTP fault condition is detected the FLG White goods, appliances pin is pulled low. For the SiP32429, the fault flag will release Flat panel displays 150 ms after the fault condition is cleared, and the switch Set top boxes, game consoles will automatically turn on at the programmed slew rate. For Smart meters, medical analyzers the SiP32419, the switch will remain off and the fault flag will remain on. The switch will be reset by toggling either control Industrial 4.0 IoT signal on EN pin or the input power if it is not under over Telecom network temperature fault condition. RF LNA power These devices feature a low voltage control logic interfac e SSD drive, data storage which can be controlled without the need for level shifting. These devices also include a power good flag. SiP32419 and SiP32429 are available in a space efficient DFN10 3 mm x 3 mm package.
