SIP32419DN-T1-GE4

SiP32419 is load switches that integrate multiple control features that simplify the design and increase the reliability of the circuitry connected to the switch. Both devices are 56 m switches designed to operate in the 6 V to 28 V range. An internally generated gate drive voltage ensures good RON linearity over the input voltage operating range.

The SiP32419 have 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 7 ms, the switch shuts off automatically. The SiP32419 has an over temperature protection circuit (OTP) which will shut the switch off if the junction temperature exceeds about 135 °C. The OTP circuit will release the switch when the temperature has decreased by about 40 °C of hysteresis.

When an OCP or an OTP fault condition is detected the FLG pin is pulled low. For the SiP32419, the switch will remain off and the fault flag will remain on. The switch will be reset by toggling either control signal on EN pin or the input power if it is not under over temperature fault condition.

These devices feature a low voltage control logic interface which can be controlled without the need for level shifting. These devices also include a power good flag. SiP32419 is available in a space efficient DFN10 3 mm x 3 mm package.
