Key Featrues
Stand-Alone Linear 1-Cell Li+ Battery Charger: The MAX1508 operates independently without requiring external components like FETs, reverse-blocking diodes, or current-sense resistors. This simplifies design and reduces the overall footprint, making it ideal for compact handheld devices.
Programmable Fast-Charge Current (0.8A max): The charger allows for adjustable fast-charge currents up to 0.8A, enabling faster charging times while maintaining safety and efficiency, which is crucial for portable electronics with limited charging windows.
Proprietary Die-Temperature Regulation Control (+100°C): The integrated thermal regulation ensures the device operates within safe temperature limits, preventing overheating and enhancing reliability, especially in high-temperature environments or during prolonged charging cycles.
Input Power-Source Detection Output (Active-Low ACOK): This feature provides a signal to indicate the presence of a valid power source, improving system efficiency by enabling power management and reducing unnecessary power consumption when no source is detected.
Low Dropout Voltage (130mV at 0.425A): The low dropout voltage minimizes power loss during charging, improving energy efficiency and extending battery life, which is particularly beneficial for devices with tight power budgets or limited battery capacity.
