説明
The ISL95522A is a highly versatile combination battery charger configurable for operating as either a Hybrid Power Boost (HPB) charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or 4-cell batteries. Both configurations allow the battery to work with the adapter to supply the system load when it exceeds the adapter capability, which is referred to as system Turbo mode. The HPB charger configuration reverse-boosts battery energy to the system bus to help the adapter provide the system power in Turbo mode. The NVDC charger configuration quickly turns on BGATE, which enables the battery to help the adapter provide the system power in Turbo mode.
The device uses N-channel MOSFETs (NFETs) for all the switches to achieve the best performance and lowest BOM cost. The internal charge pump can turn on all the NFETs quickly or slowly, depending on the circumstance or need. The ability to quickly turn on NFETs prevents system bus voltage drop when the battery is suddenly removed in Turbo mode or Battery Learn mode.
This battery charger IC provides many protection features, including a PROCHOT# indicator for system low voltage, adapter overcurrent, battery overcurrent, or overheating, with an array of SMBus programmable parameters for maximum flexibility. It also features a hardware-based adapter current limit and battery current limit in addition to SMBus programmable limits.
The ISL95522A provides a high-accuracy adapter current monitor, battery current monitor, and system power monitor outputs. To provide maximum flexibility for working with high and low power systems, it provides several configurable current sense resistor value options to achieve the best trade-off of current sensing accuracy vs. power loss.
The ISL95522A uses the Renesas Robust Ripple Regulator (R3™) modulation scheme to provide excellent light-load efficiency and fast dynamic response. The ISL95522A is available in a 32 Ld 4mm × 4mm QFN package.
