The MAX6336US23D3-T (hereinafter referred to as the MAX6336) is a supervisor-type power management integrated circuit (PMIC) designed to monitor power supply rails and provide system reset functionality in order to prevent system malfunctions caused by out-of-range events. It is one of the most versatile and widely used PMICs owing to its wide range of applications and robust features.

The MAX6336 serves many important roles in embedded systems. First, it is used to monitor and regulate the power supply voltages within a system to prevent out-of-range events by issuing a reset signal when necessary. Second, it also helps improve overall system reliability by providing over-voltage protection and latching functions. Third, it has a wide range of applications due to its comparators and delay timing generator functions. Lastly, it is a cost-effective solution for low-voltage systems.

The MAX6336 is available in a 16-pin TSSOP package and requires a 2.5V to 5.5V input voltage range. It has an operating temperature range of -40°C to +85°C and is specified for 5V operation. It features four-channel comparators with open drain outputs that can be configured to generate a reset signal when the monitored voltage reaches a set trip point. Each reset signal can be delayed independently, allowing for the system to reset within microseconds. Additionally, the MAX6336 has an active low reset output pin that can be used to reset the core processor and other ICs in the system.

The MAX6336 also has an Over-Voltage Protect (OVP) circuit to protect against out-of-range voltage events. It works by disturbing the system reset signal when the input voltage exceeds the set trip point. This prevents system electronics from becoming damaged due to excessive voltages. Additionally, the OVP circuit has a latching function that allows it to remain active even after the over-voltage event is over. This ensures that the system remains off until the voltage is returned to within its operating range.

In addition to its powerful reset and OVP features, the MAX6336 also features a watchdog timer with an adjustable timeout period. The watchdog timer is used to test the system’s normal time operation and generate a reset signal if the system’s operation time exceeds the pre-defined period. This is important for ensuring system stability and preventing issues that can result from undesired program execution or system lockups.

The MAX6336 also has an integrated delay timer that allows for setting the reset delay time from 0.02 seconds to 2.2 seconds. This gives system developers the flexibility to design their system with various reset delay times based on their application requirements. An integrated low-voltage detection circuit allows for further power regulation and improved system reliability.

The MAX6336 is an ideal PMIC for many applications, including battery-powered or portable applications. In addition, it is ideal for industrial or automotive applications since its sophisticated monitoring and reset mechanisms provide improved system reliability. With its wide range of features and adjustable reset delay, the MAX6336 is a cost-effective solution that can be applied in many applications.
