Overview
Regulator ICs Trickle-charge IC for two-cell, lithium-ion batteries BA3170 The BA3170 is a trickle-charge IC developed for two-cell, lithium-ion batteries.
The IC includes a charge control circuit, a charge output transistor, and an LED driver for showing the charging status.
FApplications Lithium-ion (two cell) battery chargers, and charging circuits FFeatures 1) Output voltage can be varied using an external resistor.
2) The output pin is PNP output with low saturation voltage.
3) Built-in output current limiting circuit protects batteries from excessive current, and prevents destruction of the IC due to output shorts.
The initial charge current is set to a low value (the current limit pin...
