MAX6758UTZD3+T Application Field and Working Principle

The MAX6758UTZD3+T, from Maxim Integrated, is a precision micropower supervisory circuit for monitoring an analog output for digital feedback loop control systems. It is an ultra-low-power device with a typical supply current of only 180 nA, and it draws only 14 nA of quiescent current with a very low 10uA hysteresis. This device has been designed for use in audio and digital video applications, and for various automotive, industrial, medical, and computer peripheral applications.

The MAX6758UTZD3+T features a wide operating voltage range of 1.8V to 5.5V, a programmable trip point, and a status flag output. The programmable trip point is adjustable over a span of 1.25V to 5.5V, while the status flag output is a logic-low output that indicates when a trip point is exceeded. The device also has an adjustable hysteresis of 7mV to 120mV, an active-low RESET disable input and an active-low RESET output.

The MAX6758UTZD3+T is built on a standard CMOS process and is compact size, measuring only 2.8mm x 2.5mm in a 8-pin TSSOP package. It also features a wide temperature range of -40°C to +125°C and a 500kHz operating frequency. The device is also RoHS compliant and incorporates ESD protection.

Working Principle:

The MAX6758UTZD3+T works by constantly monitoring the output voltage for irregularities. If the voltage exceeds a preset threshold, the RESET output will be driven logic low, thus signaling a fault in the voltage. The RESET output can be cleared by toggling the active-low RESET disable input. This device also has tight trip point accuracy and temperature stability, allowing it to accurately monitor even small voltage changes.

Furthermore, the device has very low quiescent current and is highly efficient in its power consumption. This makes the MAX6758UTZD3+T an ideal choice for use in low-power applications, where power consumption needs to be kept to an absolute minimum.

Conclusion:

In conclusion, the MAX6758UTZD3+T is an excellent choice for use in audio and digital video applications where power consumption needs to be kept to a minimum, and for various automotive, industrial, medical, and computer peripheral applications. It offers a wide temperature range, a high-frequency operating frequency, and high accuracy in its trip point detection. With its ultra-low-power consumption, the MAX6758UTZD3+T is an ideal choice for any low-power application.
