The SiP32429 smart load switch offers integrated multiple features that enhance controllability
and safety. Designed to operate in a wide input voltage range of 6 V to 28 V, the SiP32429
provides a settable overcurrent protection and features soft start time for slew rate control. The
ultra-fast short-circuit response and thermal shutdown provides enhanced levels of protection.
Key Benefits
• Wide operation voltage range with 6 V to 28 V input voltage
• Design flexibility with programmable switch turn-on rise time and adjustable overcurrent
protection threshold
• Protection and safety of < 1 μs short-circuit protection response time, thermal shutdown,
and input undervoltage lockout
• Convenient low-voltage control logic; Power Good and Fault Flag outputs with blanking time
• Simplified design and DFN10 3 mm x 3 mm compact package minimizes
component count

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.
