Note 2: Limits to T
A
= -40癈 are guaranteed by design.
Note 3: Default values. The charge/discharge currents are programmable through the serial interface (see the Register Map and
Description section).
Note 4: Default values. The current-limit thresholds are programmed through the I
2
C-compatible serial interface (see the Register
Map and Description section).
Note 5: Functional test is performed over thermal shutdown entering test mode.
Note 6: This is the default value. Threshold can be programmed through serial interface R23h[2:0].
Note 7: AC disconnect works only if (V
