100mA/200mA/300mA Current-Limit Switches
with Low Shutdown Reverse Current
General Description
The MAX4914B/MAX4915A/B/MAX4917A/B family of
switches feature internal current limiting to prevent
damage to host devices due to faulty load conditions.
These analog switches have a low 0.2Ω on-resistance
and operate from a 2.3V to 5.5V input voltage range.
They are available with guaranteed 100mA, 200mA, and
300mA current limits, making them ideal for SDIO and
other load switching applications.
When the switch is on and a load is connected to the
port, a guaranteed blanking time of 14ms ensures that
the transient voltages settle down. If after this blanking
time the load current is greater than the current limit,
the MAX4914B/MAX4915B/MAX4917B latchoff versions
enter a latchoff state where the switch is turned off and
FLAG is issued to the microprocessor. The switch can be
turned on again by cycling the power or the ON pin.
Benefits and Features
●● Guaranteed Current Limit: 100mA, 200mA, 300mA
●● Thermal-Shutdown Protection
●● Reverse Current Protection
●● 0.2Ω On-Resistance
●● 14ms Guaranteed Blanking Time
●● FLAG Function
●● 80μA Supply Current
●● 8μA Latchoff Current
(MAX4914B/MAX4915B/MAX4917B)
●● Autoretry (MAX4915A/MAX4917A)
●● 0.01μA Shutdown Current
●● 2.3V to 5.5V Supply Range
●● Undervoltage Lockout
The MAX4915A/MAX4917A have an autoretry feature
where the switch turns off after the blanking time and
then continuously checks to see if the overload condition
is present. The switch turns on and remains on after the
overload condition disappears and FLAG deasserts.
●● Fast Current-Limit Response Time (5μs)
The MAX4914B is available in the tiny 6-pin μDFN
(2mm x 2mm) package, while the MAX4915A/B and
MAX4917A/B are available in both 6-pin μDFN (2mm x
2mm) and space-saving 5-pin SOT23 packages. These
devices operate over the -40°C to +85°C extended
temperature range.

Detailed Description
Reverse Current Protection
The MAX4914B/MAX4915A/B/MAX4917A/B are forward/
reverse current-limited switches that operate from a +2.3V
to +5.5V input voltage range and guarantee a 100mA,
200mA, and 300mA minimum current-limit threshold for
different options. The voltage drop across an internal sense
resistor is compared to two reference voltages to indicate a
forward or reverse current-limit fault. When the load current
exceeds the preset current limit for greater than the faultblanking time, the switch opens and FLAG asserts.
All devices limit the reverse current (VOUT to VIN) from
exceeding the maximum IREV value. The switch is shut
off and FLAG is asserted if the reverse current-limit condition
persists for more than the blanking time. This feature
prevents excessive reverse currents from flowing through
the device to the source. When the device is in shutdown
(VON < VIL), the current from OUT to IN does not exceed
1μA (max).
The MAX4915A/MAX4917A have an autoretry function
that turns on the switch again after an internal retry time
expires. If the faulty load condition is still present after the
blanking time, the switch turns off again and the cycle is
repeated. If the faulty load condition is not present, the
switch remains on. During this retry time, FLAG remains
low until the fault is removed.
Toggle ON high to enable the current-limited switches.
The switches are continuously on only if VIN exceeds
the UVLO threshold (typically 2V) and there is no fault.
When a forward/reverse current fault is present or the die
exceeds the thermal-shutdown temperature of +150°C,
OUT is internally disconnected from IN and the supply
current decreases to 8μA (latchoff). The switch is now
operating in one of its off states. The switch-off state also
occurs when driving ON low, thus reducing the supply
current (shutdown) to 0.01μA (typ). Table 1 illustrates the
ON/OFF state.
The MAX4914B/MAX4915B/MAX4917B do not have the
autoretry option, and the switch remains in latchoff mode
until the ON pin or the input power is cycled from high to
low and then high again.
Switch-On/Off Control
The undervoltage-lockout (UVLO) circuit prevents erroneous
switch operation when the input voltage goes too low.

FLAG Indicator
All devices feature a latched fault output, FLAG. Whenever
a fault is activated, it latches the FLAG output low and
also turns the switch off. FLAG is an open-drain output
transistor and requires an external pullup resistor from
FLAG to IN. During shutdown (VON < VIL), the pulldown
on the FLAG output is released in order to limit power
dissipation. FLAG goes low when any of the following
conditions occur:
●● The die temperature exceeds the thermal-shutdown
temperature limit of +150°C.
●● The device is in current limit for more than the faultblanking period.
●● VIN is below the UVLO threshold.
www.maximintegrated.com
For the MAX4915A/MAX4917A (autoretry versions),
FLAG stays low until the overcurrent condition is removed
(See Figure 2).
Autoretry (MAX4915A/MAX4917A)
When the forward or reverse current-limit threshold is
exceeded, tBLANK timer begins counting (Figure 2). The
timer resets if the overcurrent condition disappears before
tBLANK has elapsed. A retry time delay, tRETRY, is started
immediately after tBLANK has elapsed, and during that
time, the switch is latched off. At the end of tRETRY, the
switch is turned on again. If the fault still exists, the cycle
is repeated. If the fault has been removed, the switch
stays on.

Reset the switch by either toggling ON (Figure 3a) or

Fault Blanking
All devices feature 14ms (min) fault blanking. Fault blanking
allows current-limit faults, including momentary shortcircuit faults that occur when hot-swapping a capacitive
load, and also ensures that no fault is issued during
power-up. When a load transient causes the device to
enter current limit, an internal counter starts. If the loadtransient fault persists beyond the fault-blanking timeout,
FLAG asserts low. Load-transient faults less than tBLANK
do not cause a FLAG output assertion. Only current-limit
faults are blanked.

Blanking
The autoretry feature saves system power in the case of
an overcurrent or short-circuit condition. During tBLANK,
when the switch is on, the supply current is at the current
limit. During tRETRY, when the switch is off, the current
through the switch is zero. Instead of observing the full load
current, the switch sees the equivalent load current
times duty cycle or ISUPPLY = ILOAD x tBLANK/(tBLANK +
tRETRY). With a typical tBLANK = 37ms and typical tRETRY =
555ms, the duty cycle is 6%, which results in a 94% power
savings over the switch being on the entire time. The duty
cycle is consistent across the process and devices.
Latchoff
(MAX4914B/MAX4915B/MAX4917B)
When the forward or reverse current-limit threshold is
exceeded, the tBLANK timer begins counting. The timer
resets if the overcurrent condition disappears before
tBLANK has elapsed. The switch is shut off if the overcurrent
condition continues up to the end of the blanking time.
www.maximintegrated.com
The devices have a thermal-shutdown feature to protect
the devices from overheating. The switch turns off and
FLAG goes low immediately (no fault blanking) when the
junction temperature exceeds +150°C. The switch turns
back on when the device temperature drops approximately
by 15°C.
Applications Information
Input Capacitor
To limit the input-voltage drop during momentary output
short-circuit conditions, connect a capacitor from IN to
GND. A 0.1μF ceramic capacitor is adequate for most
applications; however, higher capacitor values further
reduce the voltage drop at the input and are recommended
for lower voltage applications.
Output Capacitance
Connect a 0.1μF capacitor from OUT to GND. This capacitor
helps prevent inductive parasitics from pulling OUT
negative during turn-off, thus preventing the devices from
tripping erroneously. If the load capacitance is too large,
the current may not have enough time to charge the
capacitance and the device assumes that there is a faulty
load condition. The maximum capacitive load value that can
be driven from OUT is obtained by the following formula:
C MAX <
IFWD_MIN × t BLANK _MIN
