PMIC - Voltage Reference: REF6130IDGKR Application Field and Working Principle

Voltage references are semiconductor devices used in many applications to maintain a constant reference voltage level.

The REF6130IDGKR is a monolithic precision voltage reference device produced by Texas Instruments. It features a wide operating voltage of 2.5V to 16V and a high output voltage accuracy of ±0.01%. This device also features excellent temperature stability and line regulation.

This voltage reference can be used in a variety of applications, such as industrial and consumer high-precision voltage reference circuit design and high-precision data acquisition, linear and switched-mode power supplies, and battery charge controllers.

The device\'s internal architecture consists of an amplifier and a temperature-compensated voltage reference, with an accuracy-bypass function. The amplifier provides a high output impedance with low noise, while the temperature-compensated voltage reference provides a stable output voltage over a wide temperature range. The accuracy-bypass function allows the device to maintain its accuracy despite line or load fluctuations.

The device also features an integrated current source load switch. This switch eliminates the need for an external loading resistor, allowing the device to easily interface with resistive loads. It also features an integrated fold-back protection circuit, which helps to protect against current overloads.

The device can use an external resistor to set the output voltage. This resistor is connected between the VREF pin and ground. The reference voltage is then calculated as VREF = VREFn + (VREFp - VREFn) x (1 - R/RREF).

In summary, the REF6130IDGKR is a monolithic precision voltage reference device that features a wide operating voltage, a high output voltage accuracy, excellent temperature stability, and an integrated current source load switch. It can be used in a variety of applications, including industrial and consumer high-precision voltage reference circuit design, linear and switched-mode power supplies, and battery charge controllers.
