摘要： A temperature detector comprises temperature sensing circuitry calibration circuitry, and power regular circuitry. The temperature sensing circuitry has an output that varies with a temperature to create a temperature variation. The calibration circuitry is coupled to receive the output that varies with temperature to create a temperature variation. The calibration circuitry interprets the temperature variation and outputs a value that represents the temperature. The power supply regulator circuitry coordinates power to the temperature sensing circuitry. Alternate embodiments of the temperature detector comprise temperature sensing circuitry, calibration circuitry, and resolution enhancement circuitry. The temperature sensing circuitry has an output that varies with a temperature to create a temperature variation. The calibration circuitry is coupled to receive the output that varies with temperature to create a temperature variation. The calibration circuitry also interprets the temperature variation and outputs a value that represents the temperature. The value has a resolution. The resolution enhancement circuitry is coupled to the calibration circuitry that enhances the resolution of the value.

摘要： An integrated circuit temperature detector (thermometer) uses a temperature dependent oscillator to count up to a fixed number and thereby generate a time interval indicative of the temperature (a temperature-to-time converter). The time-to-number converter provides a numeric temperature output. Counting oscillations of a relatively temperature independent oscillator for the time interval may digitize the temperature measurement. Calibration and successive approximation iterations permit simple hardware to achieve good accuracy.

摘要： A rechargeable battery pack with low powered, gas gauge circuitry for monitoring and accumulating various operating parameters of the rechargeable battery pack, includes a current monitor for measuring the current flow into and out of a battery cell in the rechargeable battery pack. An integrated current accumulator connected to the current monitor is used to maintain a measure of the net charge having flowed into and out of the battery cell. A charging current accumulator, which is also coupled to the current monitor, is used to maintain a measure of the total charge having flowed into the battery cell, while a discharging current accumulator is used to maintain a measure of the total charge having flowed out of the battery cell. A highly accurate oscillator is used to drive the accumulators to greatly increase the accuracy of the gas gauge functions derived therefrom.

摘要： A method for monitoring various parameters and conditions of a rechargeable battery to accurately determine the remaining charge level of the rechargeable battery, and includes using a temperature sensor to monitor the temperature of the rechargeable battery. The potential level of the rechargeable battery is monitored with a voltage meter coupled to the rechargeable battery.

A current accumulator coupled to the current meter is used to accumulate the net total of current flow, an oscillatory circuit is used to generate a timing signal to time selected functions, and a timestamp will be generated indicative of a time when the battery ceases to be charged such that a self discharge correction is capable of being calculated.
