PMIC - Supervisors

The TCM809MENB713 is a Programmable RGB LED Supervision device, designed to provide optimal voltage monitoring and supervise multiple DC power supply rails. It has a wide range of applications, and it operates by adjusting the brightness of an RGB LED. This supervision device can be utilized to provide an alert when a monitored rail falls below or rises above a specified voltage level.

TCM809MENB713 Application Field

The TCM809MENB713 is designed with applications in high voltage products, ATX power supplies, automotive systems, and computers with multiple power domains. It has a wide operating temperature range to suit both commercial and industrial applications. Some of the key features of this device include an adjustable lower-over voltage threshold and an adjustable upper-over voltage threshold. It also has an adjustable under-voltage threshold that can be used to monitor slow drifts in voltage.

Some of the features of the device include a precision voltage monitoring and a built-in delay to prevent false alarms. It also has a programmable timeout period in the event of a voltage fault. This is useful to prevent unnecessary and repetitive warnings.

TCM809MENB713 Working Principle

The TCM809MENB713 is a voltage supervisor controller that works in conjunction with a RED-Green-Blue (RGB) LED. When the the voltage goes above or below a certain threshold, the controller will turn the LED on or off with the different colors corresponding to either a voltage high or voltage low.

The device has two types of comparators, one that is responsible for monitoring the higher and one for monitoring the lower voltages. The comparators will detect when the voltage is above or below a certain pre-set threshold and trigger the PWM signal that controls RGB LED.

The TCM809MENB713 was designed to replace Electroluminescent displays (EL) and Backlit LCDs, due to its advantages in more applications and improved performance. It has the ability to display a warning quicker than an EL due to its faster response time to the voltage changes. This device can also be programmed to display various warning sequences.

The device also has the flexibility of being able to adjust the voltage threshold using analog inputs. This makes it more suitable for applications with varying supply rails such as computers with multiple power domains.

Conclusion

The TCM809MENB713 Programmable RGB LED Supervision device is a versatile device that provides optimal voltage monitoring and supervising multiple DC power supply rails. It is designed for applications with a wide range of voltages and temperatures and it has a precision voltage monitoring feature. The device is suitable for applications including high voltage products, ATX power supplies, automotive systems, and computers with multiple power domains.
