   产品概述 返回TOPRH4嘉泰姆

The CXLB7373 combines a constant-current/constant-voltage linear single cell Li+ battery charger with a low dropout linear regulator. Both charger and linear regulators can work independently. The small DFN-10 package and low external component count make the CXLB7373 ideally suit to portable applications. The charger of CXLB7373 provides 0.7A charge current with thermal regulation protection to optimize the board design for compact size and typical thermal conditions. When the junction temperature reaches the thermal regulation threshold, the charger does not shut down but simply reduces the charge current. The charge current can be programmed by connecting an external resistor from the ISET pin to the GND. Using an external MOSFET to disconnect the resistor from the ground shuts down the charger, and reduces the input current down to 25mA. The CXLB7373 also has the STAT pin to indicate charge status. The LDO regulator of CXLB7373 can deliver up to 150mA current and dropout voltage is only 200mV. The 4mA low quiescent current makes it ideally suit to battery-power systems. The LDO regulator also has built-in current limit and thermal shutdown protection
