TYPICAL PERFORMANCE CHARACTERISTICS

Step-Up Rechargeable Battery Charger

Step-Up/Step-Down Rechargeable Battery Charger

• Charging current =0.8A, Auto Cut-Off at 0.25% -Delta-V point and fault conditions (RIF sets the charging current).

• VDD must be lower than VBAT.

• Short circuit condition is protected with a 2A fuse.

• Fast charge current =0.8A when VDD<VBAT, = (VDD-VBAT-0.5)/0.82 when VDD>VBAT.

• Trickle charge current = 30mA (RIF sets fast charge current, RIT sets trickle charge current).

• Typical efficiency = 75%.

• With short circuit protection.
