PMICs - or Programmable Mixed-Signal Integrated Circuits - refer to a family of integrated circuits that can be used to power microelectronic devices such as microprocessors, wireless radios, and system on chip (SoC) designs. PMICs are composed of various components, such as vREGs, supervisors, lighting drivers, analog and digital converters, battery chargers, power switches, and power allocation circuits.The MAX809RTRG is a representative PMIC of the Supervisors category - it is designed to protect electronic devices from a variety of hazardous events, whether from internal or external sources.

MAX809RTRG provides a low-cost, power-on reset generation for microcontroller-based designs and microcomputer-based systems. It offers several features, such as precision reset timing, high accuracy for voltage-level detection, and reset output assertion time. It also has a wide operating voltage range of 3.2V to 27V, making it suitable for a variety of applications, from automotive to industrial, that require a stable and accurate power-on reset.

The MAX809RTRG application field includes automotive, industrial, and communication designs, such as microcontrollers, microprocessors, system on chip (SoC) designs, power management chips, and various embedded system designs. It is particularly suitable for low-voltage automotive applications, such as LED lighting, that require a stable and reliable power-on reset. The MAX809RTRG reset generator is also a good option for microprocessor/microcontroller-based systems that require a high-accuracy reset timing.

The working principle of the MAX809RTRG involves two main functions: voltage-level detection and reset output time generation. The device is equipped with an internal voltage divider that compares an external voltage to an internal reference. If the external voltage exceeds the reference voltage by a fixed amount, the voltage detection circuit detects that the voltage level has been exceeded and triggers the reset generator block. The reset generator block then generates a reset output pin that can be used to initiate the reset process.

The device is also configured with an internal delay circuit, which allows for a precise timing adjustment for the reset output. Further, the device has a built-in hysteresis whose value can be adjusted to eliminate false triggering of the reset output. The MAX809RTRG reset generator can also operate in the power-saving mode, allowing the reset timing to be adjusted while consuming minimal power.

The MAX809RTRG is an ideal solution for providing a reliable and accurate power-on reset for embedded systems. It is designed to offer a low-cost, high-accuracy reset generator for both automotive and industrial applications. The device features an adjustable precision delay to reduce false triggering of the reset output, and it is capable of operating in a power-saving mode so that it consumes minimal power. Thanks to its wide operating voltage range, it can be used in a variety of designs, from automotive to industrial. The MAX809RTRG provides a stable, reliable power-up reset for embedded systems.
