Demonstration circuits 1645A-A, 1645A-B, 1645A-C and 1645A-D feature the LTM8061, a 32V, 2A μModule® Li-Ion battery charger. Operating from a 6.5V to 32V input source, the 1645A-A and 1645A-B demo circuits charge single cell Li-Ion batteries to float voltages of 4.1V or 4.2V respectively.
The MCP1631HV Digitally Controlled Programmable Current Source Reference Design is used to drive and dim one or more power LEDs in a series or parallel topology (depending on the LED’s capability). The reference design may also be used to charge one to four cell NiMH/NiCd or one to two cell Li-Ion battery packs. The board uses the MCP1631HV high-speed analog PWM controller and PIC16F616 microcont…
The L6924D is a fully monolithic battery charger dedicated to single-cell Li-Ion/Polymer battery packs. It is the ideal solution for space-limited applications, like PDAs, handheld equipment, cellular phones, and digital cameras. It integrates all of the power elements (the power MOSFET, reverse blocking diode and the sense resistor) in a small VFQFPN16 (3 x 3mm) package.
The bqSWITCHER series are highly integrated Li-Ion and Li-Pol switch-mode charge management devices targeted at a wide range of portable applications. The bqSWITCHER series offer integrated synchronous PWM Controller and PowerFETs, high-accuracy current and voltage regulation, charge conditioning, charge status, and charge termination, in a small thermally enhanced QFN package. The system-control…
The MCP1630 Multi-Bay Li-Ion Charger is used to evaluate Microchip’s MCP1630 used in a SEPIC power converter application. The MCP1630 Multi-Bay Li-Ion Charger is capable of charging two single-cell, Li-Ion battery packs in parallel utilizing an input voltage of 10V to 30V (battery packs are not included).
Demonstration circuit DC512B is a single battery switching step-down charge controller featuring the LTC4100.
The MCP7383XEV-DIBC AC/USB Dual Input Battery Charger Evaluation Board demonstrates Microchip's stand-alone Linear Li-Ion Battery Charger. In this case the MCP73837 with Power-Good Monitor function. The MCP73837 require only minimum components to implement a complete battery charge management circuit.
The MCP7383XEV-DIBC AC/USB Dual Input Battery Charger Evaluation Board demonstrates Microchip's stand-alone Linear Li-Ion Battery Charger. In this case the MCP73838 with Timer Enable function. The MCP73838 require only minimum components to implement a complete battery charge management circuit.
The MCP1630 Low-Cost Li-Ion Battery Charger is used to evaluate Microchip’s MCP1630 in a SEPIC power converter application. As provided, the MCP1630 Low-Cost Li-Ion Battery Charger is capable of charging a single-cell, Li-Ion battery pack from an input voltage of 6V to 18V.
The MCP73855 Battery Charger Evaluation Board is set up to evaluate simple, stand-alone, linear charging of single cell Li-Ion/Li-Polymer battery packs (the battery packs are not included). The board design provides constant current charging followed by constant voltage charging with automatic charge termination.
