The MCP1630 NiMH Battery Charger Demo Board has two LEDs. D
is used to indicate when input power is available. When the +12V input is connected,
D
These can be off, red, green or both on (amber). To conserve energy, D
illuminated when there is no input power. If both LEDs are off, that is an indication there
is no power supplied to the board input.
Under normal power-up conditions, the charger will begin with a 50 mA trickle charge.
The microcontroller will then check the status of the batteries to ensure that they are
present, their temperature is within range and the series voltage is within specified
charging limits. For visual LED charge status, a dual-color SOT-23 LED is used (D
With no input connected and 4 NiMH batteries used as a load, the MCP1630 NiMH
Battery Charger Demo Board will consume approximately 29 μA from the battery.
A temperature sensor is provided for charge termination. The sensor (U2) is located on
the back of the printed circuit board. To utilize this feature, batteries should be in
physical contact with the temperature sensor.
