BTS432E2 Features

Load dump and battery reverse: BTS432E2 has a load dump protection function, which can respond quickly to avoid system damage when the output current suddenly increases or decreases. In addition, it prevents reverse connection of the battery, protecting the circuit from wrong battery polarity.

Clip-on Negative Voltage Output: The device has the ability to clip-on negative voltage output, which means that the switching state can be maintained even if the output voltage is lower than ground, thus ensuring the stability and safety of the system.

Short-circuit protection: BTS432E2 has a built-in short-circuit protection mechanism. When the output terminal is short-circuited, it will quickly cut off the output to prevent excessive current from damaging switches and other components.

Current Limit: This device limits the maximum current through the switch, preventing system overload and damage. This is helpful for managing high current loads and preventing current spikes.

Thermal shutdown: The BTS432E2 has a built-in thermal shutdown function that monitors the chip temperature and cuts off the output when the temperature reaches a certain threshold to prevent damage from overheating.

Diagnostic Feedback: The device is capable of providing diagnostic feedback information such as output status, fault conditions, etc., to help users understand system operating conditions and problems.

CMOS Compatible Input: The input of BTS432E2 is CMOS compatible, which means that low-level logic signals can be used to control the switch, reducing the power consumption of the control circuit.

Electrostatic discharge (ESD) protection: Electrostatic discharge may damage electronic devices, BTS432E2 has electrostatic discharge protection function, which can protect the switch from damage when an electrostatic discharge event occurs.

Loss of ground and loss of VBB: Even in the event of loss of ground or VBB voltage, the BTS432E2 can still maintain normal operation, ensuring continued protection of the system in unstable power conditions.

Overvoltage protection: When the input voltage exceeds the specified range, BTS432E2 can detect and cut off the output to prevent damage to the system caused by overvoltage.

Under-Voltage and Over-Voltage Shutdown with Auto-Reset and Hysteresis: The device is capable of shutting down the output when the input voltage is too low or too high, and features auto-restart and hysteresis to keep the circuit stable within the proper voltage range.

In conclusion, the BTS432E2 is a feature-rich electronic switch with various protection, diagnostic and control features to protect the system from failure and damage in various applications.

BTS432E2 Applications
