52 / 110 page  AXP288 PMIC Optimized For Multi-Core High-Performance System AXP288 Datasheet V1.06 Copyright © 2014 X-Powers Limited. All Rights Reserved. 52 9.4.6 Temperature protection AXP288 has built in thermal protection for the IC itself with 3 levels of warning. Each warning level has 6.8˚C different in threshold compare to the next level and each warning level has hysteresis gap of 13.6˚C. Below are the charger responses with respect to each thermal warning level. Table 9-33 Warning AXP288 Response Level 1 Once the IC temperature exceeds this level, charger will charge at minimum charging current. When IC temperature drops below hysteresis limit, charger will automatically go back to its original charging state. Level 2 If IC temperature continue to rise and exceeds this level, charger will continue to charge at minimum charging current. Charge LED will provide indication according to Table 9-31. If IRQ is enabled in REG43H[7], IRQ will be asserted and its status can be read from REG 01H[7]. Level 3 If IC temperature exceeds this level, all the behavior is the same as level 2 but if REG8FH[2] is set to 1, IC will automatically shut down. Table 9-34 REG 43H Bit Description R/W Default 7 The PMIC temperature over the warning level 2 IRQ (OTIRQ) enable RW 0 Table 9-35 REG 01H Bit Description R/W Default 7 Indication PMIC die over temperature or not 0: not over temperature; 1: over temperature R 0 Table 9-36 REG 8FH Description R/W Default Bit 2 The PMIC shut down or not when Die temperature is over the warning level 3 0-not shut down 1-shut down RW 0 Beside built in IC thermal protection, AXP288 has the capability to sense one external thermal sensor (for battery temperature) through TS pin. |
