TEMPERATURE MEASUREMENT

The DS2761 uses an integrated temperature sensor to continually measure battery temperature.

Temperature measurements are placed in the temperature register every 220ms in two’s-complement

format with a resolution of 0.125°C over a range of

±127°C. The temperature register format is shown in

Figure 8.

PROGRAMMABLE I/O

To use the PIO pin as an output, write the desired output value to the PIO bit in the special feature

to the PIO bit disables the output driver, allowing the PIO pin to be pulled high or used as an input. To

sense the value on the PIO pin, read the PIO bit. The DS2761 turns off the PIO output driver and sets the

PIO bit high when in sleep mode or when DQ is low for more than 2s, regardless of the state of the

PMOD bit.

POWER SWITCH INPUT

The DS2761 provides a power control function that uses the discharge protection FET to gate battery

mA current source, is continuously
