PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
CE | 5 | I | Chip enable input. Active low. When CE = High, the input FET is off. Internally pulled down. |
ILIM | 7 | I | Input overcurrent threshold programming. An optional external resistor can be used to increase input overcurrent threshold. Connect a resistor to VSS to increase the OCP threshold. |
IN | 1 | I | Input power, connect to external DC supply. Connect external 0.1μF (minimum) ceramic capacitor to VSS. |
NC | 4 | — | Do not connect to any external circuit. This pin may have internal connections used for test purposes. |
OUT | 8 | O | Output terminal to the charging system. Connect external 1-μF capacitor (minimum) ceramic capacitor to VSS. |
PGATE | 3 | O | Gate drive for optional external P-FET |
VBAT | 6 | I | Battery voltage sense input. Connect to pack positive terminal through a resistor. |
VSS | 2 | — | Ground terminal |
Thermal Pad | There is an internal electrical connection between the exposed thermal pad and the VSS pin of the device. The thermal pad must be connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as the primary ground input for the device. VSS pin must be connected to ground at all times. |
