pin FuncTions
A 0.68μF capacitor is often used, which generates a timer the maximum charge current required to maintain the EOC at three hours, and a precondition limit time of 22.5 programmed operational VIN voltage, through maintain- minutes. If a timer-based termination is not desired, the ing the voltage on VINREG at or above 2.7V. If the voltage timer function can be disabled by connecting the TMR regulation feature is not used, connect the pin to VIN. pin to ground. With the timer function disabled, charging terminates when the charge current drops below a C/10
RUN (Pin K6):
Precision Threshold Enable Input Pin. The rate, approximately 200mA. RUN threshold is 1.25V (rising), with 120mV of input hys- teresis. When in shutdown mode, all charging functions are
VINREG (Pin L6):
Input Voltage Regulation Reference. The disabled. The precision threshold allows use of the RUN maximum charge current is reduced when this pin is below pin to incorporate UVLO functions. If the RUN pin is pulled 2.7V. There is a 100k resistor to GND. Connecting a resis- below 0.4V, the IC enters a low current shutdown mode tor from VIN to this pin sets the minimum operational VIN where the VIN pin current is reduced to 15μA. Typical RUN voltage. This is typically used to program the peak power pin input bias current is 10nA. If the shutdown function is voltage for a solar panel. The LTM8062/LTM8062A servo not desired, connect the pin to the VIN pin.
