Abstract:
A battery management chip circuit on the basis of an SOI process. The battery management chip circuit comprises a high-voltage multiplexer MUX, a voltage reference circuit, a Sigma-delta ADC (comprising an analog modulator and a digital filter), an SPI communication circuit, a function control circuit and a voltage value register. The battery management chip circuit is integrated on the basis of an SOI high-voltage process, and particularly, high-voltage MOS transistors adopted by the battery management chip circuit are high-voltage MOS device units on the basis of the SOI process. In addition, the present invention highlights the design of interface circuit-chopper circuit of the high-voltage multiplexer MUX and the Sigma-delta ADC, so as to describe the advantages such as decrease of difficulty of circuit design and reduction of layout area brought about when the present invention adopts the SOI process design and tape-out.

Claim (Index 8):
The battery management chip circuit on the basis of the SOI process according to  claim 1 , characterized in that a working voltage of the battery management chip circuit is 0-60V.
