THERMAL SHUTDOWN

In the event that the ADP5091/ADP5092 junction temperature

rises above 142°C, the thermal shutdown circuit turns off the

switch between the BAT pin and the SYS pin to prevent the

damage of the energy storage at a high ambient temperature. In

addition, the boost operation terminates. A 15°C hysteresis is

included, allowing the ADP5091/ADP5092 to return to operation

when the on-chip temperature drops to less than 127°C. When

exiting thermal shutdown, the boost and the energy storage

controller resume their functions.
