Because of current flow a voltage appears at the Microcontroller bat54s this voltage will be very near to PSU voltage because the device has very low drop during forward conduction.

BAT54A Schottky Diode Pinout, Equivalent & Datasheet

Cathode for first schottky diode in the device. TL — Programmable Reference Voltage. Cathode for second schottky diode in the device. In the above circuit BAT54A protects sensitive Microcontroller from reverse voltage and in a similar way we can use the device in other application circuits. The device being capable of carrying sizable currents while having low drop will lead to high efficiency which is a necessity in battery operated systems.


In the above circuit BAT54A is used dafasheet a protection diode for the microcontroller. BAT54A can be operated like any other rectifier diode and can be installed in rectifier and protection circuits.

Now for an instant consider the PSU polarity is connected wrongly. Working of circuit When the supply unit delivers power the diode gets forward biased and current starts flowing. Common Dtaasheet for the two schottky diodes in the device.

Under such state the diode gets reverse biased and based on BAT54A characteristics no current flows through the circuit during reverse bias. Eatasheet is designed to be capable of recovering from forward conduction to blocking reverse voltage taking only 5nS so that it can be operated high frequency applications.

The current flows out from the ba54a through this pin. Here the power supply unit delivers power Microcontroller while diode in series is for protection. With that the characteristics of BAT54A can be given as:.


The current flows in to the device from this pin. With that the characteristics of BAT54A can be given as: So under error connection there will be zero voltage appearing across the Microcontroller thus saving it from damage. Conducts in forward bias direction Anode connected to positive voltage and Cathode connected to ground Only leakage current up to 0.

Submitted by admin on 22 November BAT54A is used bta54a circuits where power efficiency is important. The device being designed to have low voltage drop during conduction will become necessary in low voltage circuits where conduction voltage drop cannot be afforded.
