7-Channel Precision Remote-Diode, Thermistor,
and Local Temperature Monitor
General Description
The MAX6698 precision multichannel temperature sen-
sor monitors its own temperature, the temperatures of
three external diode-connected transistors, and the
temperatures of three thermistors. All temperature
channels have programmable alert thresholds.
Channels 1, 4, 5, and 6 also have programmable over-
temperature thresholds. When the measured tempera-
ture of a channel exceeds the respective threshold, a
status bit is set in one of the status registers. Two open-
drain outputs,
OVERT
and
ALERT,
assert correspond-
ing to these bits in the status register.
The 2-wire serial interface supports the standard system
management bus (SMBus™) protocols: write byte, read
byte, send byte, and receive byte for reading the tem-
perature data and programming the alarm thresholds.
The MAX6698 is specified for an operating temperature
range of -40°C to +125°C and is available in 16-pin
QSOP and 16-pin TSSOP packages.

When the motor is turning, the waveform of the DC-DC power supply SW pin is questionable.
DC-DC powers the motor. Figure 3 shows the waveform of the SW pin of the DC-DC when the motor is powered on but not rotating; Figure 4 shows the waveform of the SW pin of the DC-DC at the moment when ...
