    产品信息

    描述 The bq24600 is a highly integrated Li-ion or Li-polymer switch-mode battery-charge controller. It offers a constant-frequency synchronous PWM controller with high-accuracy charge current and voltage regulation, charge preconditioning, termination, and charge status monitoring, The bq24600 charges the battery in three phases: preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches a minimum level. An internal charge timer provides a safety backup. The bq24600 automatically restarts the charge cycle if the battery voltage falls below an internal threshold, and enters a low-quiescent-current sleep mode when the input voltage falls below the battery voltage.特性 1.2-MHz NMOS-NMOS Synchronous Buck Converter Stand-Alone Charger Support for Li-Ion or Li-Polymer 5-V – 28-V VCC Input Voltage Range and Supports 1S-6S Battery Cells Up to 10-A Charge Current and Adapter Current High-Accuracy Voltage and Current Regulation ±0.5% Charge-Voltage Accuracy ±3% Charge-Current Accuracy Integration Internal Loop Compensation Internal Soft Start Safety Input Overvoltage Protection Battery Thermistor Sense Hot/Cold Charge Suspend Battery Detection Built-In Safety Timer Charge Overcurrent Protection Battery Short Protection Battery Overvoltage Protection Thermal Shutdown Status Outputs Adapter Present Charger Operation Status Charge Enable Pin 6-V Gate Drive for Synchronous Power Converter 30-ns Driver Dead-Time and 99.5% Max.
