STC4054GR規(guī)格書詳情

STC4054GR屬于集成電路(IC)的電池充電器。由意法半導(dǎo)體集團制造生產(chǎn)的STC4054GR電池充電器電池充電器 PMIC(電源管理集成電路)是元器件級產(chǎn)品系列,用于在電子設(shè)備中實現(xiàn)電池充電控制和充電管理功能。這些器件主要根據(jù)電池化學(xué)及其設(shè)計用于的電池數(shù)量來分類,可提供電化學(xué)電池和超級電容器安全充電所必需的電流或電壓調(diào)節(jié)和監(jiān)視功能。

Description

The STC4054 is a constant current/constant voltage charger for single cell Li-Ion batteries. No external sense resistor or blocking diode is required and its ThinSOT package make it ideally suited for portable applications. The STC4054 is designed to work within USB power specifications. An internal block regulates the current when the junction temperature increases, in order to protect the device when it operates in high power or high ambient temperature.

The charge voltage is fixed at 4.2V, and the charge current limitation can be programmed using a single resistor connectd between PROG pin and GND. The charge cycle is automatically terminated when the current flowing to the battery is 1/10 of the programmed value. If the external adaptor is removed, the STC4054 turns off and a 2μA current can flow from the battery to the device. The device can be put into Shutdown Mode, reducing the supply current to 25μA. The device also has a charge current monitor, under voltage lockout, automatic recharge. The device is packaged in TSOT23-5L.
