Evaluation and demonstration boards and kits are designed to provide a platform for the development and debugging of circuit designs, and the TPS3813Q1EVM is no different. It is a 5-VIN Voltage Monitor Device in a 1.2-mm × 1.2-mm ThinSOT with enable ground auto-reset and manual reset.

The TPS3813Q1EVM is intended for use in applications that require accurate evaluation and demonstration of 5-VIN power and voltage monitoring. It offers a cost-effective platform for development and debugging of 5-VIN voltage monitoring circuit designs. It can also be used in a wide range of applications such as industrial, automotive, and consumer applications.

The device is based on the TPS3813Q1 five-volt input voltage monitor family, which includes two voltage accuracy bands (V FB0 and V FB1 ) and two enable bands ( EN0 and EN1 ). The TPS3813Q1EVM comprises a 1.2-mm bank of power and ground contacts, two voltage inputs ( V IN ), four ground connections (GND), and two enable inputs (EN0 and EN1). The device also contains two comparators with hysteresis ( CMP ), two enable pins ( EN0 and EN1 ) and two voltage feedback pins ( V FB0 and V FB1 ).

The TPS3813Q1EVM application works by sending a control signal to the device’s comparators in order to determine whether the input voltage is within the specified voltage accuracy and enable bands. The comparator senses the voltage level and, if the voltage falls below the lower voltage accuracy band, the device’s output switch is operated and the circuit board’s supply rail is shorted to ground. The hysteresis feature of the comparator ensures that the device’s switch remains activated until the input voltage rises above the upper voltage accuracy band and hence the circuit board’s supply rail is restored to the correct voltage level. The enable pins provide an additional layer of protection and can be used to prevent the voltage monitoring from occurring when the enable signal is held low.

In addition to the two voltage accuracy bands, the TPS3813Q1EVM includes two sets of over-voltage and under-voltage window settings. The over-voltage window setting allows for a warning signal to be sent when the input voltage rises above a specified value. The under-voltage window setting performs the opposite function and can be used for signaling when the input voltage falls below a predetermined level.

The TPS3813Q1EVM is an ideal platform for evaluating and demonstrating 5-Vin voltage monitoring circuits, and can be used for a variety of applications, including industrial, automotive, and consumer applications. It provides users with an easy to use platform for the development and debugging of 5-VIN voltage monitoring circuits, and is suitable for a wide range of applications.
