CSE7759B
CSE7759B is a single-phase multi-function metering chip that provides high-frequency pulse CF for electric energy metering, and can directly read the relevant parameters of current, voltage, and power (such as coefficient and period) through UART. It has a serial port with a baud rate of 4800 bps (2%), with 8 bits of data, 1 bit of even check, and 1 stop bit. Typical use cases include single-phase multipurpose watt-hour meters, metering sockets, digital display meters, etc., where voltage, current, and power need to be measured.
Main features and functions of the chip
1.Cumulative electric quantity error is ± 2%.
2.See Section 2.3 for the effective value of current and voltage and power error range.
3.The baud rate of the serial UART communication protocol is 4800 bps.
4.Built in power monitoring circuit, when the power supply voltage drops to 4 V, the chip enters the reset state.
5.Built in 2.43 V voltage reference source.
6.5 V single power supply, with working current less than 5 mA.
