GATE Voltage
A curve of Gate Drive vs. V
CC
is shown in Figure 13.
GATE is clamped to a maximum voltage of 18V above the
input voltage. At a minimum input-supply voltage of 33V,
the minimum gate drive voltage is 10V. When the input
supply voltage is higher than 20V, the gate-drive voltage
is at least 10V and a standard n-channel MOSFET can be
used. Using the MAX5947 in applications over a 9V to
20V range, a logic-level N-FET must be used with a prop-
er protection Zener diode between its gate and source
(see D1 in Figure 5).
Thermal Shutdown
If the MAX5933_/MAX5947_ die temperature reaches
+150癈, an overtemperature fault is generated. As a
result, GATE goes low and turns the external MOSFET off.
The MAX5933_/MAX5947_ die temperature must cool
down below +130癈 before the overtemperature fault
condition is removed.
