Description
Low−Battery Detector Input and Enable. With this pin pulled down below 0.5 V, the device will be disabled
and will enter shutdown mode
1.195 V Reference Voltage Output, bypass with 0.1 mF capacitor if this pin is not loaded, with a 1.0 mF
bypassing capacitor, this pin can be loaded up to 2.5 mA @ VOUT = 3.3 V.
Output Voltage Feedback Input
Ground
Power Output. OUT provides bootstrap power to the IC
Battery supply input pin and connection for internal Ring−Killer
N−Channel and P−Channel Power MOSFET Drain
Auto Discharge Input
Low−Battery Detector Input
Open−Drain Low−Battery Detector Output. Output is Low when VLBI is < 500 mV.
LBO is high impedance shutdown
