Features:

During normal operation, the INPUT pin is electrically connected to the gate of the internal power MOSFET through a low impedance path.The device then behaves like a standard power MOSFET and can be used as a switch from DC up to 50KHz. The only difference from the user's standpoint is that a small DC current I_ISS (typ.100mA) flows into the INPUT pin in order to supply the internal circuitry.

The device integrates:
- OVERVOLTAGE CLAMP PROTECTION:internally set at 45V, 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 inductive loads.

- LINEAR CURRENT LIMITER CIRCUIT:limits the drain current ID to Ilim whatever the INPUT pin voltages. When the current limiter is active, the device operates in the linear region, sopower 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 overtemperature threshold T_jsh.

- OVERTEMPERATURE AND SHORT CIRCUIT PROTECTION:these are based on sensing the chip temperature and 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. Overtemperature cutout occurs in the range 150 to 190 °C, a typical value being 170 °C. The device is automatically restarted when the chip temperature falls of about 15°C below shut-down temperature.

- STATUS FEEDBACK:in the case of an overtemperature fault condition (T_j > T_jsh), the device tries to sink a diagnostic current Igf through the INPUT pin in order to indicate fault condition. If driven from a low impedance source, this current may be used in order to warn the control circuit of a device shutdown. If the drive impedance is high enough so that the INPUT pin driver is not able to supply the current Igf, the INPUT pin will fall to 0V. This will not however affect the device operation:no requirement is put on the current capability of the INPUT pin driver except to be able to supply the normal operation drive current I_ISS.

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.
