retains the last conversion result and can be read at
any time. The ADC is turned off, reducing the device
current draw to 30μA (max). The outputs of ALERT and
OVERT are latched upon entering shutdown, and the
fault queue is held in reset. After coming out of shut-
down, the Temperature register continues to read the
last converted temperature, until the next conversion
result is available.
Thermal Considerations
The MAX6633/MAX6634/MAX6635 supply current is
typically 200μA when the serial interface is inactive.
When used to drive high-impedance loads, the devices
dissipate negligible power; therefore, the die tempera-
ture is essentially the same as the package tempera-
ture. The key to accurate temperature monitoring is
good thermal contact between the MAX6633/MAX6634/
MAX6635 package and the monitored device or circuit.
Heat flows in and out of plastic packages primarily
through the leads. Short, wide copper traces leading to
the temperature monitor ensure that heat transfers
quickly and reliably. The rise in die temperature due to
self-heating is given by the following formula:
Δ T J = P DISSIPATION x θ JA
where P DISSIPATION is the power dissipated by the
MAX6633/MAX6634/MAX6635, and θ JA is the pack-
age’s thermal resistance.
The typical thermal resistance is 170°C/W for the 8-pin
SO package. To limit the effects of self-heating, mini-
mize the output currents. For example, if the
MAX6634/MAX6635 sink 4mA with the maximum
ALERT V L specification of 0.8V, an additional 3.2mW of
power is dissipated within the IC. This corresponds to a
