Introduction

The TPS3808G15DBVTG4 is an ultra-low power precision supervisor and has the capability to monitor the voltage of Li-ion battery. This device is an integrated subsystem that detects an under-voltage or an over-voltage event on the input power supply, and then issues reset or interrupt signals.

Application Field

The TPS3808G15DBVTG4 can be used in a range of applications to alert against low-voltage or excess voltage conditions. The device\'s 5.5V operating range covers all currents from 0.18mV to 6.37V, and its 0.02V voltage accuracy makes it the perfect solution for battery protection applications.

The device can be used in digital systems and portable devices, such as digital cameras, laptops, tablets and mobile phones, to protect them from over voltage or under voltage conditions. It offers two separate outputs - one for reset and one for interrupt - and up to four digital input pins which can be used to set the system up in a variety of ways. Additionally, the TPS3808G15DBVTG4 can be used in automotive applications as an engine control unit (ECU) protection, as well as in industrial systems to protect motors, drivers and other such equipment.

Working Principle

The TPS3808G15DBVTG4 operates by monitoring a voltage input reference voltage, referred to as Vin, and comparing it over time. When the voltage of Vin goes above the configured voltage threshold (Vtrip), it begins to monitor the time period between successive crossings of Vin over Vtrip. When the time between successive crossings of Vin over Vtrip is greater than the service timer (Tserv), the TPS3808G15DBVTG4 then triggers a reset. This means that the device will reset the system when the difference in voltage over a certain amount of time has exceeded the pre-set value.

Additionally, the TPS3808G15DBVTG4 has the capability to issue an interrupt signal when the input power supply drops below the configured low voltage threshold (Vlow) or when it rises above the high voltage threshold (Vhigh). This feature allows the device to be used to alert the system when its input voltage is either too high or too low. The device also has integrated push-button reset and noise filters which can be used to make sure that the reset signals are stable and reliable.

Conclusion

In conclusion, the TPS3808G15DBVTG4 is a low-power, ultra-precision supervisor suitable for a range of applications. Its input voltage range covers all current from 0.18mV to 6.37V, and its 0.02V voltage accuracy ensures it is perfectly suited for battery protection systems. It can be used to detect and alert against under-voltage or over-voltage conditions and has integrated push-button reset and noise filters. This device is a great choice for digital systems and portable devices, automotive applications and industrial systems alike.
