with Programmable Current Limit and Slew Rate Control
OPERATION DESCRIPTION
The SiP32430 is a load switch integrates multiple control
features that simplify the design and increase the reliability
of the circuitry connected to the switch. The SiP32430 is
designed to operate in the 6 V to 28 V range.
An internally generated gate drive voltage ensures low
switch resistance over the wind input voltage operating
range.
The SiP32430 has a slew rate control circuit that programs
the switch turn-on time to the value set by an external
capacitor.
An over-current protection circuit (OCP) continuously
monitors the current through the load switch. When the over
current protection is triggered, the circuit controls the switch
impedance to clamp the current to the level programmed by
an external resistor. The trigger current is typically 8 % over
the set current limit. In case the over-current condition
persists for more than 7 ms, the switch shuts off
automatically.
The SiP32430 has an over temperature protection circuit
(OTP) which will shut the switch off immediately if the
junction temperature exceeds over temperature limit of
typically 150 °C. The OTP circuit will release the switch
when the temperature has decreased by about 20 °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 SiP32430 features a low voltage control logic interface
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.
