Hi, Tahar
Thanks for your reply.
I'm going to use tps61032 for the boost circuit. There is a Low Battery Detector Circuit—LBI/LBO.
It mentioned:
"The low-battery detector circuit is typically used to supervise the battery voltage and to generate an error flag
when the battery voltage drops below a user-set threshold voltage. The function is active only when the device is
enabled. When the device is disabled, the LBO pin is high-impedance. The switching threshold is 500 mV at LBI.
During normal operation, LBO stays at high impedance when the voltage, applied at LBI, is above the threshold.
It is active low when the voltage at LBI goes below 500 mV.
"
I have a question :
1. When the voltage at LBI goes below 500 mV and LBO active low, the circuit will auto turn off? Or I need to set the EN pin once the LBO active low?
Thanks,
Gary
