The TPS3831G12DQNT device is a PMIC (Power Management Integrated Circuit) supervisor that works to protect power systems from overloaded conditions and long latencies with a wide range of features. This device belongs to the supervisors category of PMICs, which are dedicated to providing communications, power distribution, and fault management of electronic systems. The TPS3831G12DQNT offers efficient performance to provide safe and reliable protection in various power applications.

The TPS3831G12DQNT is a single-channel high-performance voltage supervisor that implements the robust features required for reliable system power-up and power-down control. Its wide supply voltage range (1.6V to 5.5V) and operating temperature range (-40°C to +125°C), make it suitable for use in extreme environment conditions. Its low quiescent current of 10.5 μA, allows the TPS3831G12DQNT to remain in continuous monitoring of the power system while keeping power draw low. Additionally, the TPS3831G12DQNT has a wide range of available output voltage and pull-ups, allowing it to perform in a variety of applications.

The TPS3831G12DQNT provides a variety of fault protection features including input overvoltage protection, power supply monitoring, power-on reset, manual reset, pin-to-pin comparators, and output fault detection. These features allow the device to detect a multitude of power supply conditions, from simple undervoltage faults and input voltage spikes, to more tedious manual reset conditions. The wide range of fault protection features, coupled with the device’s low power consumption, make it well suited for a wide variety of applications.

By default the TPS3831G12DQNT supervisor is in an active state, and provides an indication of overvoltage, input voltage, and temperature conditions. The device will enter a fault mode of operation when an overvoltage, undervoltage, or temperature fault condition is detected, and generates an active high fault signal. The TPS3831G12DQNT supervisor can be configured to generate either a manual reset or a power-on reset signal based on the fault conditions detected. The power-on reset is generated when the supply voltage drops below a predetermined threshold and is applied to the reset pin of the system microcontroller.

The TPS3831G12DQNT supervisor can be used in a wide range of power applications where reliable power up, power down, voltage monitoring, and fault detection are necessary. The wide supply voltage and temperature range, coupled with the device’s low power consumption, make it ideal for embedded systems, automotive and industrial applications, as well as in power supply circuits for portables and telecom systems. Additionally, the device is available in a QFN package, providing a compact solution for space-constrained applications.
