The TPS2400DBVT is an Overvoltage Protection Controller used with an external N-channel MOSFET to isolate sensitive electronics from destructive voltage spikes and surges. It is specifically designed to prevent large voltage transients associated with automotive environments (load dump) from damaging sensitive circuitry. When potentially damaging voltage levels are detected by the TPS2400 the supply is disconnected from the load before any damage can occur. Internal circuitry includes a trimmed band-gap reference, oscillator, Zener diode, charge pump, comparator and control logic. It is designed for use with an external N-channel MOSFET, which are readily available in a wide variety of voltages.
● Up to 100V overvoltage protection
● <1µs Overvoltage turnoff time
● External N-channel MOSFET driven by internal charge pump
● 1mA Maximum static supply current
● 2.5kV Human-body-model 500V CDM electrostatic discharge protection
● 3V Undervoltage shutdown threshold
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
