are not guaranteed until a minimum of 6.0V is applied to
the DCIN pin.
The linear regulator also incorporates a thermal shutdown
feature. If the MAX11080/MAX11081 die temperature
rises above +145°C, the device shuts down. After a ther-
mal shutdown, the die temperature must cool 15°C below
the shutdown temperature before the device restarts.
Figure 12 shows the linear regulator power-up sequence
and Figure 13 shows the low DCIN POR event.
DCIN and GND U Supply Connections
A surge voltage is produced by the electric motor
during regenerative braking conditions. The
MAX11080/MAX11081 are designed to tolerate an
absolute maximum of 80V under this condition. The
MAX11080/MAX11081 should be protected against high-
er voltages with an external voltage suppressor such as
