PIN7 – V1P1 – Internally biased to 1.1V and applied to non-inverting input of AMP2. Requires an external bypass capacitor.

PIN8 – AMP2N – Inverting input of AMP2 amplifier.

PIN9 – AMP2O – Output of the AMP2 amplifier.

PIN10 – NC – For LS6525.

PIN10 – LOBAT Output – For LS6526 only. Open drain output requiring an external pull-up resistor to a power-supply that can be higher than VDD.

An active low at the output signifies that a low battery condition exists.

PIN11 – TEST – This pin is not used and must be tied to ground.

PIN12 – INT Output – Open drain output requiring an external pull-up resistor to a power supply that can be higher than VDD. A recognized Interrupt

signal will be an active low at this output.

PIN13 – VDD – Power Supply Voltage

PIN14 – VSS – Power Supply Ground
