7 Detailed Description

The AS8510 consists of two independent high resolution 16-bit SD analog to digital conversion channels. The measurement path of these two channels integrates a programmable gain amplifier, chopper and de-chopper, sigma-delta modulator, decimator and a digital filter for simultaneous measurement of Current and Voltage/Temperature. The two measurement channels, namely the Current and Voltage/Temperature measurement channels have identical data path. The input signal is amplified in the Programmable Gain Amplifier (PGA) with any of the selected gains of 1, 5, 25, 40 and 100 facilitating measurement of a wide range of Current, voltage and temperature levels. Gain Settings for different input ranges and any associated restrictions are explained in the Table 13. Offset in the measurement path is minimized with the use of a chopper and a de-chopper at appropriate stages in the data path. By default the chopper/de-chopper is ON in the measurement path. It may be disabled by programming the appropriate register. The amplified input signal is converted into a single-bit pulse-density modulated stream by the Σ-Δ Modulator. A decimator acting as a low-pass filter filters out the quantization noise and generates 16-bit data corresponding to the input signal. The decimation ratios of 64, 128 may be selected in the first filter stage. For reducing data rate further, the second stage decimation can be used. An optional FIR Filter is provided to offer matched low pass filter response typically required in lead acid battery sensor systems.

7.1 Current Measurement Channel

The voltage across a Shunt Resistor, connected in series with the Battery negative terminal, forms the input signal to the Current Measurement channel. RSHH and RSHL are the Current measurement input pins. Offset in the input signal is nullified with the use of a chopper and a de- chopper at appropriate stages in the data path. The programmable gain amplifier in the data path with programmable settings of 1, 5, 25, 40 and 100 enables measurement of current ranges from ±1A to ±1500A. The sampled input signal is converted into a single-bit pulse-density modulated stream by the Σ-Δ Modulator. A decimator acting as a low-pass filter filters out the quantization noise and generates 16-bit data equivalent to the input current signal. The programmable input sampling rate and the decimation ratio determine the output data rates. The data path can be programmed to provide 1Hz to 2 kHz rates in the various modes available. An optional FIR filter is provided to offer matched low pass filter response typically required in lead acid battery sensor systems. After enabling the current measurement channel, the delay for the availability of the first sample is two conversion cycles.

7.2 Voltage/Temperature Measurement Channel

The other two parameters of the Battery for measurement are Voltage and its Temperature. The second channel accepts signals from four independent sources through a Multiplexer as listed below: An attenuated battery voltage obtained through appropriate external resistor divider, (or) A signal from the external temperature sensor, (or) A signal from external reference, (or) A signal from the internal temperature sensor. Apart from this difference in the multiplexing of four input signals, the rest of the data path is identical to the Current measurement channel. RSHH and RSHL are the Current measurement input pins The Battery Voltage which can go up to 18V is attenuated through a Resistor Divider externally and is applied to the Voltage Channel. For Automotive Battery measurement, the Gain of the PGA should be restricted to 5 and 25. The latency for the first result from the voltage measurement channel is two conversion cycles. A second option on this measurement channel is to measure Temperature. Internally generated constant current is pumped through the Temperature Sensor with positive temperature coefficient, and, a high- precision resistor. The voltages across the sensor and the resistor form the inputs to the measurement channel one at a time. The difference between the two voltages which is independent of the magnitude of the current is used to determine the temperature accurately. The Voltage across the sensor is applied between the ETS and VSS pins and, the voltage across the high-precision resistor is applied between ETR and VSS. External Temperature measurement involves the acquisition of two signals one after the other using the same constant current source. The latency for the first result from the temperature measurement channel is two conversion cycles. A third option on the measurement channel is to measure the internal temperature. Hence, one of the three options for measurement of Battery Voltage, External Temperature and, internal temperature may be carried out by selection of appropriate inputs through the internal multiplexer selection.
