2 / 13 page Connection Diagram and Package Mark Information LLP10 Package Drawing 20128202 Note: The actual physical placement of the package marking will vary from part to part. The package marking “X” is the manufacturing plant code. “YY” is a 2-digit date code, and "ZZ" for die traceability. These codes will vary considerably. "L111B” identifies the device (part number, option, etc.). TABLE 1. LM3658 Pin Description Pin # Name Description 1 CHG_IN AC wall adapter input pin. 2 USBpwr USB power input pin. 3 GND Power and signal ground pin. 4 USB_sel Pulling this pin low limits the USB charge current to 100 mA. Pulling this pin high limits the USB charge current to 500 mA. 5 EN_b Pulling this pin low enables the charger. Pulling this pin high disables the charger. 6 STAT2 Active low open-drain output. Indicates charger status. This pin is capable of driving an LED as well as GPIOs. See Operation Description section for more detail. 7 STAT1 Active low open-drain output. Indicates charger status. This pin is capable of driving an LED as well as GPIO. See Operation Description section for more detail. 8I SET A resistor is connected between this pin and GND. The resistor value determines the full-rate charge current when using the AC source. 9T S Battery temperature sense pin. This pin must be connected to battery pack’s temperature sense output pin. See Operation Description section for more detail. 10 BATT Positive battery terminal connection. TABLE 2. Ordering Information Order Number Package Marking Supplied As LM3658SD L111B 1000 units, Tape-and-Reel LM3658SDX L111B 4500 units, Tape-and-Reel For more information on the various options, please refer to Operation Description section. www.national.com 2 |
