The DS1336 Afterburner Chip is designed to provide power switching between a primary power supply(VCC) and a backup battery power supply (VBAT). Five VCC and two battery paths are provided which can be used individually or in parallel to supply uninterrupted power in applications such as SRAM networks.
Provides power switching of up to 1.5 amps at voltages between 3.0 and 5.0 volts
Five separate power switches
Selectable battery switches for use with
Very low on impedance of 0.7O
Battery backup current of 4 mA
Diode-isolated battery path
Available in 16-pin DIP or 16-pin SOIC surface
Low voltage drop battery path
Connects directly to a variety of Dallas Semiconductor devices, adding increased switching capability for large battery backup current applications
The MAX6439âMAX6442 are a family of ultra-low-power battery monitors with integrated microprocessor (ÂµP) supervisors. The battery monitors are offered with single or dual low-battery output options that can be used to signal when the battery is OK (enabling full system operation), when the battery is low (for low-power system operation), and when the battery is dead (to disable system operation). These devices also have an independent ÂµP supervisor that monitors VCCand provides an active-low reset output. A manual reset function is available to reset the ÂµP with a push-button. No external components are required.
The ISL88731A is a highly integrated Lithium-ion battery charger controller, programmable over the SMBus system management bus (SMBus). The ISL88731A is intended to be used in a smart battery charger (SBC) within a smart battery system (SBS) that throttles the charge power such that the current from the AC-adapter is automatically limited.
The bq29330 is a 2-series, 3-series, and 4-series cell lithium-ion battery pack full-protection analog front end (AFE) IC that incorporates a 2.5-V, 16-mA and 3.3-V, 25-mA low dropout regulator (LDO). The bq29330 also integrates an I2C-compatible interface to extract battery parameters such as battery voltage, individual cell voltages, and control output status. Other parameters such as current protection thresholds and delays can also be programmed into the bq29330 to increase the flexibility of the battery management system.
