Detailed Description
The MAX6652 is a voltage and temperature monitor
designed to communicate through an I
2
C-compatible/
SMBus interface with an external microcontroller (礐).
A 礐 with no built-in I
2
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-
working equipment. All inputs are converted to an 8-bit
code using an ADC with an oversampling ratio of 8 to
improve noise rejection. The oversampling ratio can be
reduced by a factor of 4, with a corresponding reduc-
tion in the monitoring cycle time, by setting bit 5 of the
configuration register to 1. Each input voltage is scaled
down by an on-chip resistive divider so that its output,
at the nominal input voltage, is 3/4 of the ADCs full-
scale range, or a decimal count of 192 (Table 3). Table
1 is the register map and Table 2 is the temperature
data format.

Y (bit 0) is the SMBus read/write bit. When the 7-
bit chip address is read back from the serial
address register, an 8-bit word will be presented
with a 0 in bit 0 (Y).
