ADP2291_15 Datasheet, PDF (11/20 Pages) Analog Devices – Compact, 1.5 A Linear Charger for Single-Cell Li Battery

THERMAL SHUTDOWN
If the ADP2291 junction temperature rises above 135°C,
thermal shutdown occurs. Extreme junction temperatures can
be the result of excessive current operation and/or high ambient
temperatures.
ADP2291
A 35°C temperature hysteresis is included so that the ADP2291
does not return to operation during thermal shutdown until the
on-chip temperature drops below 100°C.
