... In addition, an address code can also be directly written to the serial address register. This code will overwrite the code set by connection of the ADD pin, until the MAX6652 is taken through a power-on reset cycle. The MAX6652 features 60Hz or 50Hz line-frequency rejection for optimal performance. The device operates from +2.7V to +5.5V and is specified for operation from -40° ...

... C-compatible or SMBus capabili- ties can generate SMBus serial commands by “bit- banging” general-purpose input-output (GPIO) pins. The MAX6652 can monitor external supply voltages of typi- cally 2.5V, 3.3V, and 12V, as well as its own supply voltage and temperature. This makes it ideal for supervisor and thermal management applications in telecommunications, desktop and notebook computers, workstations, and net- Table 1 ...

... In this mode, the I SMBus interface remains active, and the supply current drops to 10µA or less. Power-On Reset (POR) The MAX6652 power-on reset supply (POR) voltage is typically 2V. Below this supply voltage, all registers are reset, the device is put into shutdown mode, and the 2 I C-compatible/SMBus interface is inactive ...
