Introduction

The TLC7725QPWRG4 device is one of Texas Instruments’ Supervisors (PMICs). It is a low-power, single-channel power supervisor designed for providing system-level hardware monitoring and control functions in portable applications, as well as a wide range of automotive, industrial, and consumer embedded designs. This device offers an array of features such as a watchdog, reset outputs, detection of power loss or brown out, and a power supply monitoring.

Application Field

The primary application field for the TLC7725QPWRG4 device is the embedded system. It can be used to monitor an entire system, or to provide system-level control of specific components. Examples include automotive electronics, consumer electronics, medical devices, motor control units, industrial control units, computer peripherals, and home appliances. The device can also be used for providing power monitoring and control for automotive safety systems.

Features & Benefits

The TLC7725QPWRG4 device offers many features and benefits, including:

• Low power consumption in standby mode
• Wide operating voltage range (2.3 V ~ 5.5 V)
• Programmable reset delay and output active period
• Programmable power loss/brown-out detection
• Programmable power supply monitoring
• Watchdog for detecting microcontroller lock-up
• Flexible reset output sequence
• Able to detect low battery status
• RTC-backup power supply monitoring
• Small footprint (3.00 mm x 3.00 mm)

The device can be programmed to provide different reset conditions according to system requirements. These actions can be triggered by a supply voltage falling below a specified limit, a watchdog timer expiring, power removal or restoration, or other system events. The device also features an active-high reset output, which provides an independent reset signal for downstream logic. The reset output can be programmed to stay low for an adjustable period after a reset event. This programmable reset delay is ideal for opening or holding reset signals during startup.

Working Principle

When the supply voltage goes above the programmed undervoltage (UV) limit, the TLC7725QPWRG4 device is enabled and will start monitoring the voltage. When the supply voltage goes below the UV limit, a reset signal is initiated by the device. The device will also detect power removal and restoration and initiate a reset signal accordingly. The power supply monitor can be programmed to detect power levels at different thresholds, and generate a signal to indicate a low battery status.

The reset signal generated by the device can be directed to two reset outputs, one active-low and one active-high. The active-low output is generated first when the device detects voltage below the UV limit, and the active-high output is generated after a programmable delay that allows the device to initialize the downstream logic. The reset output sequence can also be programmed to provide different behavior. The device also includes a watchdog timer which can be programmed to reset the device or downstream logic when it detects microcontroller lock-up.

The device features a low quiescent current in standby mode (less than 5 μA). This makes the TLC7725QPWRG4 an ideal choice for low-power applications where maximum standby current is critical. The device also features flexible reset and power supply monitoring, which makes it suitable for a range of applications.

Conclusion

The TLC7725QPWRG4 is a low-power, single-channel power supervisor designed for providing system-level hardware monitoring and control functions in portable applications, as well as a wide range of automotive, industrial, and consumer embedded designs. It offers an array of features such as a watchdog, reset outputs, detection of power loss or brown out, and a power supply monitoring. The main applications of the device include embedded systems and automotive safety systems, and it offers low power consumption, a wide operating voltage range, and a small form factor.
