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

voltage
3.3 [V] or higher
Rest voltage 2.8 [V]
The VBatt circuit operates at the edge
where the reset voltage becomes Hi.
(At this time, the output transistors are
set on and the load is put on; If this
voltage is 3.3 [V] or higher, the VBatt
circuit operates, and if it is lower than
3.3 [V], it does not start up.

Notes: 1. Use capacitors with little temperature-related capacitance fluctuation.
2. Do not provide capacitors to the Batt pin (Pin 10)
3. The reset IC must be provided externally.
