A curve of Gate Drive vs. V
GATE is clamped to a maximum voltage of 18V above the
input voltage. At a minimum input-supply voltage of 9V,
the minimum gate-drive voltage is 4.5V. 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. In applications over a 9V to 20V range, a logic-level
n-FET must be used with a proper protection Zener diode
between its gate and source (as D1 shown in
If the MAX5932 die temperature reaches +150°C, an
overtemperature fault is generated. As a result, GATE
goes low and turns the external MOSFET off. The
MAX5932 die temperature must cool down below +130°C
before the overtemperature fault condition is removed.
