GigaDevice - 1.5A Switching Charger PMIC
XProduct SKU: GD30BC2416FUTR-P
The GD30BC2416x is a highly integrated, programmable, low quiescent current power management integrated circuit (PMIC) that integrates the most common needs for wearables and low power battery applications. The GD30BC2416x integrates a switching charger of programmable charging current (up to 1.5A) and a synchronous boost converter at Typical 5V output. The IC also includes a 12-bit ADC for battery gauge monitoring, and a low quiescent current, low noise LDO capable of delivering 50mA load current. The device integrates advanced power path management and control that allow the device to provide power to the system while charging the battery even with poor adapters. The dynamic power path management automatically balances the currents delivered to the system and battery charging. A high voltage and over current protection circuit is implemented in the IC to protect it from high input voltage as high as 20V. The GD30BC2416x device supports charge current up to 1.5A and termination current down to 5mA. The maximum charge current is set at a default of 1.5A and is programmable by connecting an external resistor from ISET pin to ground. The battery is charged using a standard Li-Ion charge profile with three phases: pre-charge, constant current and constant voltage regulation. The device has several power saving modes to increase battery life whether the product is in storage or in operation. The quiescent current could be as low as 5uA when it is in sleep mode and thus most battery could sustain more than a year in shelf. The versatile features of GD30BC2416x allow for it to best used in wearable applications such as headsets, earbuds and hearing aids, or low battery applications such as smart watches and fitness accessories, or patient monitors and portable medical equipment.
