PROTECTION FEATURES

During normal operation, the Input pin is

- OVERTEMPERATURE AND SHORT CIRCUIT

electrically connected to the gate of the internal

power MOSFET. The device then behaves like a

standard power MOSFET and can be used as a

switch from DC to 50 KHz. The only difference

from the user’s standpoint is that a small DC

current (I_iss) flows into the Input pin in order to

supply the internal circuitry.

PROTECTION: these are based on sensing

the chip temperatureand are not dependent on

the input voltage. The location of the sensing

element on the chip in the power stage area

ensures fast, accurate detection of the junction

temperature. Overtemperaturecutout occurs at

minimum 150^oC. The device is automatically

restarted when the chip temperature falls

below 135^oC.

The device integrates:

- OVERVOLTAGE CLAMP PROTECTION:

internally set at 42V, along with the rugged

avalanche characteristics of the Power

MOSFET stage give this device unrivalled

ruggedness and energy handling capability.

This feature is mainly important when driving

inductiveloads.

- STATUS FEEDBACK: In the case of an

overtemperature fault condition, a Status

Feedback is provided through the Input pin.

The internal protection circuit disconnects the

input from the gate and connects it instead to

ground via an equivalent resistance of 100 Ω.

The failure can be detected by monitoring the

voltage at the Input pin, which will be close to

ground potential.

Additional features of this device are ESD

protection according to the Human Body model

and the ability to be driven from a TTL Logic

circuit (with a small increase in R_DS(on)).

- LINEAR CURRENT LIMITER CIRCUIT: limits

the drain current Id to Ilim whatever the Input

pin voltage. When the current limiter is active,

the device operates in the linear region, so

power dissipation may exceed the capability of

the heatsink. Both case and junction

temperatures increase, and if this phase lasts

long enough, junction temperature may reach

the overtemperaturethreshold T_jsh.
