MFR_TEMP_SENSOR_CONFIG (F0h)
The MFR_TEMP_SENSOR_CONFIG command is used to configure the temperature sensors. Table 26 describes the
MFR_TEMP_SENSOR_CONFIG command.

Applications Information
Power-Supply Decoupling
To achieve the best results when using the device,
decouple the V
DD power supply with a 0.1FF capacitor.
Use a high-quality, ceramic, surface-mount capacitor
if possible. Surface-mount components minimize lead
inductance, which improves performance, and ceram-
ic capacitors tend to have adequate high-frequency
response for decoupling applications.
Decouple the REG25 and REG18 regulator outputs using
1FF and 10nF capacitors (one each per output).
Do not connect other circuitry to either of these pins.
Open-Drain Pins
MSDA, MSCL, SCL, SDA, FAULT, and ALERT are open-
drain pins and require external pullup resistors con-
nected to V
DD
to realize high logic levels.
PSEN0 to PSEN5 can be user-configured as either
CMOS push-pull or open-drain outputs. When config-
ured as open-drain, external pullup resistors connected
to V
DD are required to realize high logic levels (see the
MFR_MODE settings).
BIT BIT NAME MEANING
15 ENABLE
Clearing and setting this bit reinitializes the temperature sensor.
0 = Temperature sensor disabled.
1 = Temperature sensor enabled.
14:0 0 These bits always return a 0.
