Function Description
VIN Under-voltage Lockout (UVLO)
The APL3534/A/B power switch has a built-in under-volt-
age lockout circuit to keep the output shut off until internal
circuitry is operating properly. The UVLO circuit has hys-
teresis and a de-glitch feature so that it will typically ig-
nore undershoot transients on the input. When input volt-
age exceeds the UVLO threshold, the output voltage starts
a soft-start to reduce the inrush current.
Power Switch
The power switch is an N-channel MOSFET with a low
R
DS(ON). The internal power MOSFET does not have the
body diode. When IC is in UVLO state, the MOSFET pre-
vents a current flowing from the VOUT back to VIN and
VIN to VOUT.
Current-Limit Protection
The APL3534/A/B power switch provides the current-limit
protection function. During current-limit, the devices limit
output current at current-limit threshold. For reliable
operation, the device should not be operated in current-
limit for extended period time.
Output Discharge
When the input voltage is under VIN UVLO Threshold or
V
EN=Low or VENB=High, the output discharge device is
turned on to discharge the output voltage.
Soft-Start
The APLA3534/A/B has a built-in output soft-start control
to limit the current surge during start-up. The soft-start
interval is 2.5ms.
Short-Circuit Protection
When the output voltage drops below 1.2V, which is
caused by the over load or short-circuit, the devices limit
the output current down to a safe level. The short-circuit
current-limit is used to reduce the power dissipation dur-
ing short-circuit condition. If the junction temperature is
over the thermal shutdown temperature the device will
enter the thermal shutdown. This Function is disabled
during soft-start interval.
Enable/Disable (SOT-23-5)
Pulling the ENB above 2V or EN below 0.8V will disable
the device, and pulling ENB pin below 0.8V or EN above
2V will enable the device.
When the IC is disabled the supply current is reduced to
less than 1
µA. The enable input is compatible with both
TTL and CMOS logic levels. The EN/ENB pins cannot be
left floating.
Over-temperature Protection
When the junction temperature exceeds 140
o
C, the inter-
nal thermal sense circuit turns off the power FET and
allows the device to cool down. When the device’s junc-
tion temperature cools by 20
o
C, the internal thermal sense
circuit will enable the device, resulting in a pulsed output
during continuous thermal protection. Thermal protec-
tion is designed to protect the IC in the event of over-
temperature conditions. For normal operation, the junc-
tion temperature cannot exceed T
J=+125
oC.
Output Over-Voltage Protection
The output over-voltage protection is implemented by 2
either sensing mechanisms. One is by sensing when
V
OUT voltage is above VOVP threshold, the internal power
MOSFET is turned off. The other is by sensing when re-
verse current, flowing from VOUT to VIN, surpasses I
RV.
When the reverse current reachers the reverse current
Blocking threshold, the device limits the reveres current
at I
RV threshold level. When the reverse current fault ex-
ists for more than 0.7ms, the internal power MOSFET is
turned off. The internal power MOSFET is allowed to turn-
on once the output voltage gose below V
IN-1.2V.
