I am design an smart LiPo power pack for an existing device. I need to switch on/off a LiPo cell (3.7V) from its charger and power path controller used in the existing device.
For tjat I'm intending to use a LTC1981 in the following configuration.
A bidirectional switch is necessary because the PMIC in the existing device will charge the battery when +5V is present and connect the battery to the power rail when +5V is not present.
The current will be no more than 1 A and the LTC1981 will be controlled by a tiny micro-controller powered by the battery itself.
Do you think that LTC1981 will be able to control the two MOSFETs providing a bidirectional on/off switch?
Best regards
