Function of HTL6033AAG

• Comprehensive protection featuresEquipped with high-precision voltage and current detection circuits, it offers over-voltage (OV) protection with an accuracy of ±25mV and under-voltage (UV) protection with an accuracy of ±80mV. It also provides discharge over-current (DOC) protection, short-circuit (SC) protection, and charge over-current (COC) protection. Additionally, it features built-in wire break protection, as well as high and low temperature protection for charging and discharging, effectively preventing battery damage due to abnormal temperatures.
• FET Drive CapabilityIntegrated with a field-effect transistor drive circuit, it can directly drive N-type charging and discharging tubes, facilitating control over the battery's charging and discharging process.
• Flexible Protection Delay SettingsBy adjusting the size of the external capacitor, the protection delay times for overcharge, over-discharge, discharge overcurrent 1, discharge overcurrent 2, and charge overcurrent can be set to meet the requirements of different application scenarios.
• Low-power characteristicsUnder normal conditions, the consumption current is less than 30μA, and in the power-off state, it is less than 1μA, which helps to extend the battery life by 1.
• Miniature packagingUtilizing 14-pin TSSOP and SOP packaging, featuring compact size and high integration, suitable for applications with limited space.
