TK65010
PIN DESCRIPTION
SUPPLY VOLTAGE PIN (VIN)
This pin is the positive power supply for the TK65010.
Current draw from the positive supply is typically 5 µA.
GNOUND PIN (GND)
The pin provides the ground connection for the IC.
VOLTAGE MONITORING PIN (VMON)
This pin is the voltage monitoring pin of the TK65010.
When the voltage on this pin is less than approximately
710 mV, the LBO signal will be asserted. When the voltage
on this pin is less than approximately 690 mV, the DBO pin
will be asserted. This pin is also connected to the negative
input of a high-gain op-amp. The op-amp will attempt to
maintain the voltage on this pin at 700 mV. However, the
current-sink capability of this pin is limited to the range of
0 to 580 nA.
LOW BATTERY OUTPUT PIN (LBO)
This active-low pin will be asserted when the voltage on the
VMON pin is less than approximately 710 mV; otherwise the
LBO pin will not be asserted.
DEAD BATTERY OUTPUT PIN (DBO)
This active-low output will be asserted when the voltage in
the VMON pin is less than approximately 690 mV; otherwise
the DBO pin will not be asserted.
