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.

Ground
Input Voltage. Bypass IN to GND with a low-ESR ceramic capacitor with a minimum value of 0.1µF.
Input to Current-Sense Amplifier. Connect the sense resistor between SENS and IN.
Switch Output
No Connection. Not internally connected.
Open-Load Threshold Setting Input. A resistive divider between REF, OLT, and GND sets the open-load current
threshold (MAX16913A). For the MAX16913, connect OLT to GND.
+3V Nominal Reference Output. Use a resistive divider between REF, OLT, and ground to set the open-load
current threshold (MAX16913A). The output impedance of this voltage regulator is 5kΩ.
Current-Monitor Voltage Output. AOUT can be used to measure the load current by means of an external ADC.
The output impedance is 5kΩ.
Open-Drain Open-Load Indicator Output.
OL
goes low when the load current is lower than the open-load
current threshold, or when there is a short-to-battery fault. Connect
OL
to a 10kΩ pullup resistor. See Table 1
.
Open-Drain Short-Circuit Indicator Output.
SC
goes low when the load current is greater than the short-circuit
current threshold or when there is a short-to-battery fault. Connect
SC
to a 10kΩ pullup resistor. See Table 1.
FUNCTION
SHDN Active-High Control Input. Drive SHDN low to turn on the device.
