CHG_Config Register Name Base Default CHG_Config 2-wire serial 15h Offset: 19h-3 Charger Configuration Register This is an extended register and needs to be enabled by writing 011b to Reg. 1Ch first. This register is reset at a VDD27-POR or XRES input. Bit Bit Name Default Access Bit Description 7:5 - 000 n/a 4:3 CHG_I_EOC<1:0> 10 R/W Configures the end of charge current threshold. Charging will be stopped if the current drops below the threshold. 00: 8% of constant current setting 01: 15% 10: 10% 11: 20% 2:0 VSUP_EOC <2:0> 101 R/W Defines VSUP voltage after EOC and isolated battery. 000: 4.3V 001: 4.4V 010: 4.5V 011: 4.6V 100: 4.7V 101: 4.8V 110: 4.9V 111: 5.0V Table 34. CHG_NTC Register Name Base Default CHG_NTC 2-wire serial 01h Offset: 19h-4 Charger NTC Control Register This is an extended register and needs to be enabled by writing 100b to Reg. 1Ch first. This register is reset at a VDD27-POR or XRES input. Bit Bit Name Default Access Bit Description 7:3 - 0000 0 n/a 2 NTC_MODE 0 R/W Defines the temperature level for the battery temperature supervisor to stop charging. (for beta of NTC = 4250) 0: 55ºC 1: 45ºC 1 NTC_10K 0 R/W Defines the type of NTC used for battery temperature supervisor. 0: 100k Ω 1: 10k Ω 0 NTC_ON 1 R/W Enables the battery temperature supervisor via NTC resistor. 0: NTC battery temp supervision disabled 1: NTC battery temp supervision enabled |
