HOW DOES IT WORK?
eFuse 5 Click is based on the TPS16530, an industrial eFuse from Texas Instruments. The TPS25940 provides robust protection for all systems and applications powered by an external power supply from 4.5V to 58V. Load, source, and device protections are provided with many programmable features, including undervoltage lockout selectable via UVLO SEL jumper and the fast response short circuit protection that immediately isolates the faulty load from the input supply when a short circuit is detected. The TPS16530 also allows users to program the overcurrent limit threshold between 0.6A and 4.5A via an external I2C-configurable digital potentiometer, the AD5171 from Analog Devices.
The TPS16530 can be put in low-power Shutdown mode using the EN pin of the mikroBUS™ socket, offering a switch operation to turn ON/OFF the eFuse. It also allows flexibility to configure the device between the two current-limiting fault responses (latch off and auto-retry). Selection is made by positioning SMD jumpers marked MODE SEL to the appropriate position marked GND or NC (GND is for automatic restart mode response during current limit and thermal fault, while NC is for latch off).
For system status monitoring and downstream load control, the TPS16530 provides one fault signal, which can be visually detected via the red FLT LED or the FLT pin on the mikroBUS™ socket, and a precise current monitor output available on the MON pin of the mikroBUS™ socket. Besides, the TPS16530 also features an open drain Power good (PGDD) indicator output, which can control downstream loads like DC/DC converters.
This Click board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
