ICs - Reduces Component Count and Solution Size AND TEC I INNOVAT O L OGY SiP32429 N HN POWER ICs O 19 62-2012 SiP32429 Load Switch The SiP32429 switch integrates multiple control features that simplify the design and increase the reliability of the circuitry connected to the switch. An internally generated gate drive voltage ensures good RON linearity over the input voltage operating range. The SiP32429 has a slew rate control circuit that controls the switch turn-on time to the value set by an external capacitor. After soft start, an over current protection circuit (OCP) continuously monitors the current through the load switch, and controls the switch impedance to limit the current to the level programmed by an external resistor. If the over current condition persists for more than 6 ms, the switch shuts off automatically. The SiP32429 has an over temperature protection circuit (OTP) which will shut the switch off immediately if the junction temperature exceeds 140 °C. The OTP circuit will release the switch when the temperature has decreased by about 30 °C of hysteresis. When an OCP or an OTP fault condition is detected the FLG 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 device features a low-voltage control logic interface that can be controlled without the need for level shifting. The device also includes a power good flag.
