TMI4054 Overview
The TMI4054 is a plete constant-current and constant-voltage linear charger for single cell Li-ion battery application. The default battery charge voltage is fixed at 4.2V, and the charging current can be programmed by external resistor on PROG pin. The charging current could be programmed up to 800mA with good system thermal design.
