LiPoly Lader - Single Cell 3.7-7V Eingang

Produktbeschreibung

Lipo Lader für eine Zelle auf Basis des MAX1555 Ladecontrollers von Maxim.
Eingangspannung von 3,7-7 Volt


This is a Polymer Lithium Ion battery charger based on the MAX1555 IC. This charger uses either USB bus power (MAX1555 internally limits this to 100mA) or 2.1mm center positive wall-wart power (MAX1555 internally limits this to 300mA). Current is automatically reduced to a trickle when charging is complete. Cheap, easy to use, and flexible, this board serves as a great demo board for the MAX1555. This charger is a 'must have' for quick and clean charging of Lithium Polymer chemistry batteries.

Features:

• Intelligent IC monitored charging - Constant current/Constant Voltage
• Do not use this charger to charge NiMH, NiCd, or any other battery type
• Comes fully assembled and tested
• Single Cell Charger
• Requires 3.7V to 7V(max!) Input
• MAX1555 will automatically choose the wall-wart charging if both USB and barrel jacks are connected to power
• Separate header for external power in
• Separate headers for battery and load system so batteries don't have to be removed for charging
