The CXLB7372 is a constant-current/constant-voltage linear charger for single cell Li+ batteries. The CXLB7372 needs no external MOSFETs or diodes, and accepts input voltages up to 6.5V. The small package and low external component counts make the CXLB7372 an idea part for portable applications。On-chip thermal regulation protects the ACXLB7372from excessive temperature and optimizes 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. Charge current can be programmed by connecting an external resistor from ISET pin to GND. Using an external MOSFET to disconnect the resistor from ground shuts down the charger, and reduces the input supply current down to 25mA. The ACXLB7372also has the STAT pin to indicate charge status. The ACXLB7372is available in a SOT-23-5 package, and operates over the -40°C to +85°C temperature range
