MXD1817UR23+T

Introduction

The MXD1817UR23+T is an advanced supervisor IC specifically designed for general purpose applications within industrial, automotive, automotive physical layer (PHY), and handheld/portable device applications. The supervisor is designed to respond to input voltage signals. It offers flexibility in reset timing versus supply voltage ratio by allowing the setting of thresholds to define the reset timing versus supply voltage. The IC is provided with a POR (power-on reset) and SRF (supervisory reset function) functionality, offering reset and reset interrupt capabilities.

Application Field

The MXD1817UR23+T is used in industrial, automotive, automotive physical layer (PHY), and handheld/portable device applications. Automotive applications wherein high reliability and low power consumption are essential requirements typically benefit from the reset and reset interrupt features of the MXD1817UR23+T.

Working Principle

The working principle of the MXD1817UR23+T is based on the detection and comparison of input voltages. The detection part is used to detect any abnormality of the supply voltage compared to the specified thresholds. Upon detecting any abnormality, this part transfers the abnormality status to the comparison part where the reset level and reset timing can be controlled. In addition, the voltage monitored by the ICcan be programmed via its external resistors to create a voltage monitor zone. When the monitored voltage drops outside of the monitor zone, the IC issues a reset and an interrupt signal while setting its status flags.

Conclusion

The MXD1817UR23+T is an advanced IC specifically designed for industrial, automotive, automotive physical layer (PHY), and handheld/portable device applications. It offers flexibility in reset timing versus supply voltage ratio by allowing the setting of thresholds to define the reset timing versus supply voltage. The working principle of the MXD1817UR23+T comes from the detection of input voltages, followed by the comparison of the detected voltage to predetermined thresholds. When the monitored voltage drops outside of the monitor zone, the IC issues a reset and an interrupt signal.
