APPLYING A LOAD TO THE MCP1630 LOW-COST NIMH BATTERY
CHARGER REFERENCE DESIGN
1. To apply a load to the MCP1630 Low-Cost Li-Ion Battery Charger, the positive
side of the load (B+) should be connected to pin 1 of J2. The negative side of the
load (B-) should be connected to pin 5 of J2. Care should be taken when using
electronic loads or ground referenced loads.
2. A thermistor referenced to (B-) in the battery pack should be utilized, recom-
mended EPCOS Inc. PN B57509m103A5. If a thermistor is not available or not
desired, a 10 k Ω resistor should be placed between pins 4 and 5 of the battery
header (J2).
3. The installed firmware will prevent the board from entering the 1.3A Fast Charge
mode, if the battery terminal voltage is less than 2V. During power-up, the board
will always trickle charge first, so using a purely resistive load will not work for
trickle and fast-charge current. The best way to evaluate the charger is to use a
three series cell NiMH 2,200 mA/hour batteries, or the recommended simulated
battery load. Refer to Figure 2-3 before applying a load to the MCP1630
Low-Cost NiMH Battery Charger Reference Design.
