Table 1-1 lists the input and output connections available on this EVM and their respective descriptions.
|
I/O Connector |
Description |
|---|---|
| J1 – VIN / GND | Input voltage from external power supply, recommended 5 V. Max operating input voltage is 6.6 V, OVP trip point. Max input voltage is 30 V while in OVP. |
| J2 – OUT (BAT+) / GND (BAT-) / GND / BIAS | Battery connection, connect 10-k? resistor to BIAS or use 10 k? on PCB (JP6). |
| JP1 – VSET ADJ. | Disable R9, default is installed. |
| JP2 – REG / IN / OUT |
Source voltage for housekeeping regulator, U2. Default Input voltage IN. |
| JP3 – PG (Power Good) LED | Default setting is ON. |
| JP4 – ISET | Sets Fast Charge Current. Fixed = 400 mA ADJ = R22 range 60 mA to 600 mA |
| JP5 - STAT LED | Default setting is ON. |
| JP6 – BIAS | Fixed=10 k. |
| JP7 | Not used, do not install |
| JP8 | Not used, do not install |
|
JP9 |
Not used, do not install |
Table 1-2 lists the S1 switch positions for VSET and their respective descriptions. Use only one postion ON, do not combine.
