Power Management Integrated Circuit (PMIC) technology has become an integral part of any electronic device, as it ensures system stability, efficiency and reliable operation. PMICs offer a wide range of features such as voltage regulation, current and temperature monitoring, power sequencing, etc. All these features make it attractive and suitable for the most demanding applications. OnePlus of the more popular PMIC solutions is the TLC7733IDR, a single small-footprint device that provides comprehensive control of power management in a system, from power-on/off, supervisor, reset and to power sequencing.

TLC7733IDR Overview

The TLC7733IDR is a multichannel ultra-low power supervisor with an integrated regulator for transportable electronic devices. This device includes four monitoring channels and an adjustable output voltage regulator (1.70V and 5.0V). The four monitoring channels provide four independent and adjustable reset thresholds, providing support for analog and digital sensors, and a 0.1μF capacitor in each channel provides a low-response time protect feature. The output voltage regulator can be employed to power other functions within the system. The TLC7733IDR provides a high level of sophistication in power management, which frees the system from the need of external components and manual jumper settings. Additionally, due to its small footprint and low power consumption, the device is suitable for portable and battery powered applications.

Working Principle

The TLC7733IDR is a customizable power management solution that can provide reset and power sequencing capabilities for a system. It is designed to operate from 3V and 5.5V, with a low quiescent current of 0.5 μA. The device takes advantage of standby current, error current, response time and rising time measurements to control power management.When the device is powered up, an open-drain signal, RESETB, is generated at the RESET pin. This signal can be used to power other devices in the system. Additionally, the RESETB signal can be used to detect the power-on reset and power-off reset events of a system.The device also features four individual voltage threshold settings that enable the user to control the reset response of the device. The four channels are independent and can be configured to detect various analog or digital inputs. Once activated, the device will generate the RESETB signal. This signal can be used to reset or power-off the system.Finally, the device also contains an adjustable output voltage regulator that can be used to power other system components. The regulator is adjustable from 1.70V to 5.0V and can provide up to 100 mA of current. This feature eliminates the need for an external voltage regulator, allowing for a more compact design.

Conclusion

With its array of features, the TLC7733IDR is an ideal choice for any application requiring comprehensive power management. With its low power consumption and compact design, the device is suitable for use in portable and battery-powered applications. Additionally, its adjustable output voltage regulator and four individual voltage threshold settings allow for greater control of system power management. Combined, these features make the TLC7733IDR an excellent choice for a wide range of applications.
