_______________________________________________________________________________________
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
Active-High Control Input. Drive SHDN low to turn on the device.
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.
