LA5619M
Lead Battery Charger IC with Battery
Voltage Detection Function
Overview
The LA5619M is a single-chip IC that integrates a battery
voltage detection function and a lead battery charger to
support compact sets.
Functions
• Charge voltage can be switched between cycle voltage
and trickle voltage (4.9 V typ. → 4.6 V typ.).
• Charge current limit can be set with an external resistor
(125 mA typ.).
• Built-in charge current detection circuit
• Built-in battery voltage detection circuit
