Maxim Integrated\'s MAX795RCSA+T is an ultra-low-voltage reset supervisor with push-pull and open drain reset, digital reset threshold comparator, and system voltage detector. The part offers high flexibility and is especially useful when conforming to a wide range of input supply voltage ranges without the need for external components or software revisions. In this article, we explore the application field and working principle of the MAX795RCSA+T.

Application Field

The MAX795RCSA+T is ideal for applications in which reset capability is required for high-speed, low-power operation. It is especially useful for cellular phone applications, where reliable power-on reset operation over a wide range of supply voltages is required. The wide supply voltage range (1.7V to 5.5V) makes the part ideal for low-power applications, while also addressing the need for low-voltage reset circuitry. In addition, the MAX795RCSA+T offers tight reset operating temperature range, high-reset accuracy, and low quiescent supply current.

Working Principle

The MAX795RCSA+T operates on a two-state, push-pull and open-drain reset system. It uses a digitally-controlled comparator to detect a voltage level below a preset threshold for reset insertion. This preset threshold can be adjustable in small increments using an external resistor. When the part detects a low voltage value, it executes reset insertion. The open-drain outputs can be used to enable external reset circuitries and logic gates.

The MAX795RCSA+T also uses a system voltage detector, which can be programmed in order to detect a low-voltage system error. When this condition occurs, the output pin is pulled down. In addition, the MAX795RCSA+T offers an adjustable reset delay circuit. This circuit can be used to delay the reset signal to allow for longer reset signalling times. The part also offers a low-power sleep mode, which reduces the quiescent current draw. This feature allows the MAX795RCSA+T to be used in low-power applications.

The MAX795RCSA+T is designed to operate over an extended temperature range (-40°C to +85°C), with tight reset thresholds and low quiescent current. It is available in two package variants - the ultra small 0.48mm x 0.45mm package and the standard 5-pin SOT23 package. The part is highly reliable, with no false reset trips or retry failures.
