Power management integrated circuits (PMICs) provide essential power management functions for products and applications powered by microcontrollers, embedded processors, and other devices. Supervisors, a type of PMIC, help to ensure that the device is kept powered at the right voltage and frequency as intended. The TPS3705-50D is an accurately adjustable voltage supervisor IC that can monitor either an analog or an input voltage, provide adjustable voltage precision, and expand the operational voltage range.

The TPS3705-50D has adjustable Voltage Precision Noise suppressor (VPON) technology, which allows the user to adjust accuracies to the micro voltage level and features an operating voltage range of 1.2V to 3.6V. This device also provides ±8% accuracy margins over the entire operating temperature range. It has an active current consumption of <250nA, which is comparable to the industry’s best power consumption for devices of this kind. Other features of this device include a programmable reset time interval, a reset active output delay that can be selected from a number of options, and an adjustable threshold voltage.

The TPS3705-50D is well suited for a variety of applications, including systems that require low power consumption, higher margin accuracy and better noise immunity. It is used in consumer electronics and industrial systems such as electric vehicles, medical equipment, power supplies, and consumer appliances. Additionally, this device can be used in applications where a reset IC is required, such as battery management systems, product activation and similar applications. Additionally,The TPS3705-50D is useful for enterprise storage applications that demand reliable power management, as well as automotive and consumer applications that require power-on reset.

The TPS3705-50D works by monitoring the DC power rails of the system. If the input voltage is outside the user-defined threshold voltage, the device will issue a reset.This reset is active for a programmed time interval before returning to normal operation. During this time interval, the reset output remains active with an adjustable reset active state delay. This delay can be selected from a number of options, ranging from 10µs to 10s. The device also features a VPON input which has the ability to filter out noise in the system.

In summary, the TPS3705-50D is a voltage supervisor IC with adjustable voltage precision and an operating voltage range of 1.2V to 3.6V. It features low current consumption, programmable reset time interval, adjustable reset active output delay, and adjustable threshold voltage. This device is suited to a wide range of applications, including consumer electronics, electric vehicles, medical equipment, power supplies, consumer appliances, and enterprise storage systems.
