Trickle Charger Register (10h)
Programmable Trickle Charger
The simplified “Programmable Trickle Charger” schematic shows the basic components of the trickle charger. The
trickle-charge select (TCS) bits (bits 4 to 7) control the selection of the trickle charger. To prevent accidental enabling, only
a pattern of 1010 on the TCS bits enables the trickle charger. All other patterns disable the trickle charger. The trickle
charger is disabled when power is first applied. The diode-select (DS) bits (bits 2 and 3) select whether or not a diode is
connected between VCC and VBACKUP. The ROUT bits (bits 0 and 1) select the value of the resistor connected between VCC
and VBACKUP. Table 6 shows the bit values.
Table 6. Trickle Charger Register (10h)
Warning: The ROUT value of 250
Ω must not be selected whenever V
CC is greater than 3.63 V.
