MAX6652
Overview
The MAX6652 system supervisor monitors multiple power-supply voltages, including its own, and also features an on-board temperature sensor. Voltages and temperature are converted to an 8-bit code using an analog-to-digital converter (ADC).
- The MAX6652 I2C™-compatible/SMBus interface also responds to the SMB alert response address. The 2-wire serial interface accepts both I2C and standard system management bus (SMBus) write byte, read byte, send byte, and receive byte commands to program the alarm thresholds and to read voltage and temperature data. Voltage data is scaled so that when the nominal voltage is present at a pin (e.g., 3.3V for the 3.3VIN pin), the conversion result is equal to 3/4 of the ADC full-scale range or a decimal count of 192 (Table 3). The temperature data format is 7 bits plus sign, with each data bit representing 1°C, in two's complement format (Table 2). The MAX6652 has only one address pin, ADD. One of four different address codes can be selected by connecting the ADD pin to GND,
