12V/5V Hot-Plug Switch
General Description
The MAX34561 is a dual, self-contained, hot-plug switch
intended to be used on +12V and +5V power rails to limit
through current and to control the power-up output-volt-
age ramp. The device contains two on-board n-channel
power MOSFETs that are actively closed-loop controlled
to ensure that an adjustable current limit is not exceed-
ed. The maximum allowable current through the device
is adjusted by external resistors connected between the
LOAD and ILIM pins.
The device can control the power-up output-voltage
ramp. Capacitors connected to the VRAMP pins set
the desired voltage-ramp rate. The output voltages
are unconditionally clamped to keep input overvoltage
stresses from harming the load. The device also contains
adjustable power-up timers. Capacitors connected to
the TIMER pins determine how long after power-on reset
(POR) the device should wait before starting to apply
power to the loads. The TIMER pins can be driven with
a digital logic output to create a device-enable function.
The device contains an on-board temperature sensor
with hysteresis. If operating conditions cause the device
to exceed an internal thermal limit, the device either
unconditionally shuts down and latches off awaiting a
POR, or waits until the device has cooled by the hyster-
esis amount and then restarts.
