PMIC - Supervisors are broadly used in Electronics for the purpose of maintaining essential power levels and are a must for many digital circuit designs. The TPS3707-33D is a supervised Power Management Integrated Circuit (PMIC) developed by Texas Instruments. The objective of this article is to discuss the application field and working principles of the TPS3707-33D module.

Overview of the TPS3707-33D

The TPS3707-33D is an advanced power management IC designed for portable electronic devices such as portable phones, music players, digital cameras, MP3 players, and personal digital assistance/handheld organizers. This surface mountable device features low quiescent current, wide supply voltage range, low input voltage dropout, and low start-up current. It is an 8-lead TSOP-8 package device, measuring 3.041mm x 3.910mm.

The TPS3707-33D features various operating modes and programmable trip points to improve system reliability. Since the TPS3707-33D can be ordered in versions with multiple voltages and trip points, it provides designers with flexibility in terms of application optimization. The device offers a wide variety of protections such as voltage tracking, power-down modes, under-voltage lockout, output short-circuit protection, over-temperature protection, and ramp-up to turn-on delays. In addition, it has adjustable reset timing, a voltage detector reset output, and adjustable reset assurance timer for ensuring a minimum voltage at the reset output.

Application Fields of the TPS3707-33D

The TPS3707-33D is designed for use in portable electronic devices such as cellular phones, PDAs, MP3 players, digital cameras, and portable gaming consoles. It ensures system reliability by providing various protections and adjustable trip points. Its low quiescent current and wide supply voltage range make it suitable for use in a range of power management applications.

The device is suitable for a multitude of applications such as battery-powered systems, high-side monitoring, system power sequencing and sequencing of battery-backed power rails, electronic load-switching load sequencing, high-side reset, or power-on reset of microprocessors. It also provides emergency switch-off and LED fault-indication functions. It is designed to reduce total system cost and power consumption while increasing system reliability. It is suitable for use in automotive, medical, and consumer applications.

Working Principle of the TPS3707-33D

The TPS3707-33D utilizes a voltage detector circuit to monitor the user-defined voltage level and outputs a reset signal when the voltage level is lower than a preset threshold. The device is equipped with an adjustable trip point that allows the user to set the threshold voltage level at which the reset signal is triggered. The voltage detector circuit monitors the voltage of its input constantly, and when the input voltage falls below the desired threshold, the output of the voltage detector is asserted, pulling the reset signal low.

In addition, the TPS3707-33D has an adjustable reset assurance timer which keeps the reset signal asserted for a predetermined amount of time regardless of the input voltage. This feature eliminates the possibility of temporary low voltage dips from causing unexpected reset signals. Furthermore, the device is equipped with short-circuit protection and over-temperature protection for increased system reliability.

Conclusion

The TPS3707-33D is an advanced power management IC developed by Texas Instruments. It is suitable for use in portable electronic devices such as cellular phones, PDAs, MP3 players, digital cameras, and portable gaming consoles. With its adjustable trip points and wide operating temperature range, the TPS3707-33D ensures system reliability and cost reduction. The device is equipped with several protections such as voltage tracking, power-down modes, under-voltage lockout, and output short-circuit protection. Its working principle involves a voltage detector circuit that monitors the user-defined voltage level and outputs a reset signal when the voltage level is lower than a preset threshold.
