WSON10 Package Drawing Pin Descriptions 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. 8 ISET A resistor is connected between this pin and GND. The resistor value determines the full-rate charge current when using the AC source. 9 TS Battery temperature sense pin. This pin must be connected to battery pack’s temperature sense output pin. For the LM3658SD-B version, leaving this pin open indicates that the battery pack is not present. The charger IC will invoke LDO mode if this pin is left floating. See Operation Description section for more detail. 10 BATT Positive battery terminal connection. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. ABSOLUTE MAXIMUM RATINGS (1) (2) (3) CHG_IN, USBpwr (VCC) −0.3V to +6.5V All other pins except GND −0.3V to CHG_IN or USBpwr Power Dissipation (4) Internally Limited Junction Temperature (TJ-MAX) +150°C Storage Temperature Range −65°C to +150°C ESD Rating (5) Human Body Model: 2.0 kV Machine Model: 200V (1) All voltages are with respect to the potential at the GND pin. (2) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits and associated test conditions, see the Electrical Characteristics tables. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) The LM3658 has built-in thermal regulation to regulate the die temperature to 120ºC. See Operation Description section for more detail. (5) The Human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. The machine model is a 200 pF capacitor discharged directly into each pin.
