HL7046

The HL7046 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with power path management for space-limited portable applications. The HL7046 takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously. The charger function features pre-charge (PRE.C), fast current (CC), constant voltage (CV) regulation, charge termination, and auto-recharge. The power path management function ensures continuous power to the system by automatically selecting either input or battery, or both. This function features a low dropout regulator from the input to the system. The power path management separates charging current from the system load, which allows for proper charge termination and keeps the battery in full-charge mode. The HL7046 provides a system short-circuit protection (SCP) function by limiting the current from the input to the system and the battery to the system. This feature is especially critical for preventing the Li-ion battery from being damaged due to an excessive high current. An on-chip battery under-voltage lockout (UVLO) cuts off the path between the battery and the system if the battery voltage drops below a programmable battery UVLO threshold. This prevents the Li-ion battery from being over-discharged. An integrated I²C control interface allows the HL7046 to program the charging parameters, such as input current limit, input minimum voltage regulation, charging current, battery regulation, charging current, battery regulation voltage, safety timer, and battery UVLO.

HL7046 is a highly integrated single-cell lithium-ion/lithium polymer battery charger IC with power path management functionality, suitable for small-sized portable devices. HL7046 can power the system load using an AC adapter or USB port while also charging the battery independently. It also includes pre-charge (PRE.C), fast constant current charging (CC), and constant voltage (CV) regulation functions, as well as charge termination control and automatic recharging capabilities. The power path management function ensures continuous power supply to the system by automatically selecting either the input or the battery or both. This feature includes a low dropout regulator from the input to the system and a switch from the battery to the system. The power path management function separates the charging current and system load, allowing for appropriate charge termination and keeping the battery in a fully charged state.
