MAXIM MAX14523AL

19-4814; Rev 0; 7/09
250mA to 1.5A, Adjustable
Current-Limit Switches
Features
The MAX14523A/MAX14523AL/MAX14523B/MAX14523C
programmable current-limit switches feature internal
current limiting to prevent damage to host devices due
to faulty load conditions. These current-limit switches
feature a low 70mΩ on-resistance and operate from a
+1.7V to +5.5V input voltage range. The current limit is
adjustable from 250mA to 1.5A, making these devices
ideal for SDIO (secure digital input/output) and other
load-switching applications.
Each device in the family handles an overcurrent event
differently depending on the option selected. The
MAX14523A/MAX14523AL go into an autoretry mode,
the MAX14523B latches off the switch, and the
MAX14523C features a continuous current-limit mode.
Additional safety features include thermal shutdown to
prevent overheating and reverse-current blocking to
prevent current from being driven back into the source.
The MAX14523A/MAX14523AL/MAX14523B/MAX14523C
are available in a tiny 8-pin, 3mm x 3mm, TDFN package and operate over the -40°C to +125°C automotive
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX14523A/MAX14523AL/MAX14523B/MAX14523C
programmable current-limit switches operate from
+1.7V to +5.5V and provide internal current limiting
adjustable from 250mA to 1.5A. These devices feature
a fixed blanking time, and a FLAG output that notifies
the processor when a fault condition is present.
Programmable Current Limit/Threshold
A resistor from SETI to GND sets the current
limit/threshold for the switch (see the Setting the
Current Limit/Threshold section). If the output current is
limited at the current threshold value for a time equal to
or longer than tBLANK, the output flag asserts and the
MAX14523A/MAX14523AL enter the autoretry mode,
the MAX14523B latches off the switch, and the
MAX14523C enters the continuous current-limit mode.
8
Autoretry (MAX14523A/MAX14523AL)
When the forward current reaches the current threshold, the tBLANK timer begins counting (Figure 2). FLAG
asserts if the overcurrent condition is present for
tBLANK or longer. The timer resets if the overcurrent
condition disappears before the blanking time (tBLANK)
has elapsed. A retry time delay (tRETRY) starts immediately after the blanking time has elapsed. During that
time, the switch latches off. At the end of tRETRY, the
switch turns on again. If the fault still exists, the cycle
repeats. If the fault has been removed, the switch stays
on. During this cycle, FLAG stays low. In autoretry, if
the die temperature exceeds +170°C (typ) due to self
heating, the MAX14523A/MAX14523AL go into thermal
shutdown until the die temperature drops by approximately 15°C (see the Thermal Shutdown section.)
_______________________________________________________________________________________
250mA to 1.5A, Adjustable
Current-Limit Switches
ILOAD = ILIM [(tBLANK )/(tBLANK + tRETRY)]
With a typical tBLANK = 17.5ms and typical tRETRY =
560ms, the duty cycle is 3%, resulting in a 97% power
savings over the switch being on the entire time.
Latchoff (MAX14523B)
When the forward current reaches the current threshold, the tBLANK timer begins counting (Figure 3). FLAG
asserts if an overcurrent condition is present for greater
than tBLANK time. The timer resets if the overcurrent
condition disappears before t BLANK has elapsed.
The switch turns off if the overcurrent condition continues beyond the blanking time. Reset the switch by
either toggling the control logic (ON or ON) or cycling
the input voltage. If the die temperature exceeds
+170°C (typ) due to self heating, the MAX14523B goes
into thermal shutdown until the die temperature
drops by approximately 15°C (see the Thermal
Shutdown section).
Continuous Current Limit (MAX14523C)
When the forward current reaches the forward-current
threshold, the MAX14523C limits the output current to
the programmed current limit. FLAG asserts if the current limit is present for tBLANK and deasserts when the
overload condition is removed. In this mode, if die temperature exceeds +170°C (typ) due to self heating, the
MAX14523C goes into thermal shutdown until the die
temperature drops by approximately 15°C (see the
Thermal Shutdown section).

SWITCH STATUS
Switch-On/Off Control
The ON input for the MAX14523A/MAX14523B/
MAX14523C and ON input for the MAX14523AL control
the switch, see Table 1. Toggle ON for the MAX14523B
to reset the fault condition once the short-circuit current
is detected and the device shuts down.
Reverse-Current Protection
The MAX14523A/MAX14523AL/MAX14523B/MAX14523C
feature a reverse-current protection circuit that limits
the backflow current to 2µA when the reverse-current
protection circuitry has tripped. The switch turns off and
FLAG asserts without waiting for tBLANK to elapse. The
switch turns back on and FLAG deasserts when VIN V OUT drops below the reverse-current threshold by
95mV (typ).
FLAG Indicator
FLAG is an open-drain fault indicator output and
requires an external pullup resistor to a DC supply.
FLAG goes low when any of the following conditions
occur:
•
•
The blanking time has elapsed
The reverse-current protection has tripped
•
•
The die temperature exceeds +170°C
SETI is connected to ground.
Thermal Shutdown
Thermal-shutdown circuitry protects the devices from
overheating. The switch turns off and FLAG goes low
immediately when the junction temperature exceeds
+170°C (typ). The switch turns on again after the
device temperature drops by approximately 15°C (typ).
Applications Information
Setting the Current Limit/Threshold
A resistor from SETI to ground programs the current
limit/threshold value for the MAX14523A/MAX14523AL/
MAX14523B/MAX14523C. Table 2 lists various current
limit/thresholds set by different resistor values at SETI.
Leaving SETI unconnected selects a 0 current
limit/threshold. Connecting SETI to ground asserts
FLAG.
Use the following formula to calculate the current limit:
RSETI(kΩ) =
141400(V)
− 2.48(kΩ)

MAX14523A/MAX14523AL/MAX14523B/MAX14523C
The autoretry feature saves system power in case of an
overcurrent or short-circuit condition. During tBLANK
time, when the switch is on, the supply current is held
at the current limit. During time tRETRY, when the switch
is off, the current through the switch is zero. Thus, the
average output current is much less than the programmed current limit. Calculate the average output
current using the following equation:

as short as possible to reduce the effect of undesirable
parasitic inductance. Place input and output capacitors
as close as possible to the device (no more than 5mm).
IN and OUT must be connected with wide short traces
to the power bus. During normal operation, the power
dissipation is small and the package temperature
change is minimal. If the output is continuously shorted
to ground at the maximum supply voltage, the operation of the switches with the autoretry option does not
cause problems because the total power dissipated
during the short is scaled by the duty cycle:
P(MAX) =
Do not use an RSETI value smaller than 91.78kΩ.
Note: Connecting any capacitance larger than 20pF to
SETI can cause instability.
IN Bypass Capacitor
Connect a minimum of 1µF capacitor from IN to GND to
limit the input voltage drop during momentary output
short-circuit conditions. Larger capacitor values further
reduce the voltage undershoot at the input.
VIN(MAX) × IOUT(MAX) × tBLANK
tRETRY + tBLANK
Attention must be given to the MAX14523C continuous
current-limit version when the power dissipation during
a fault condition can cause the device to reach the thermal shutdown threshold.
Chip Information
PROCESS: BiCMOS
OUT Bypass Capacitor
Pin Configuration
For stable operation over the full temperature range
and over the full-programmable current-limit range, use
a 1µF ceramic capacitor from OUT to ground.
Excessive output capacitance can cause a false overcurrent condition due to decreased dv/dt across the
capacitor. Calculate the maximum capacitive load
(CMAX) value that can be connected to OUT using the
following formula:
CMAX (µF) =
