PMIC - Voltage Reference

Voltage reference devices are widely used in applications that need to provide constant voltages. These devices are typically used in applications such as power supplies, microcontroller/microprocessor-based designs, OSD circuits, switching regulator applications, linear regulator applications, etc. Voltage reference devices often offer a wide selection of voltage levels, and offer high accuracy, very low voltage offset drift and excellent power regulation.

The ZR2431N801TA is a PMIC voltage reference produced by Zilog. It is an ultra-low power, 1.8V bandgap voltage reference. The substrate is temperature compensated, making it one of the most accurate temperature-stable voltage references available. The ZR2431N801TA employ an innovative patented current-mode control loop to ensure stability and accuracy even with significant capacitive loads. This makes it ideal for applications like battery management, where the voltage reference need to maintain its accuracy even in noisy environments.

The device has an input voltage range from 1.8V to 3.6V and an output voltage range from 0.8V to 1.5V. The maximum output current of the device is 20mA and it has a typical active current consumption of 11µA. The ZR2431N801TA is able to maintain a high power supply rejection over a wide range of frequency, and is also very efficient at converting a wide range of input voltages into a stable output voltage.

The device also comes with built-in fault protection. The internal error amplifier is able to detect any over/under voltage fault and generate an interrupt signal. Additionally, the device also has an active enable pin which allows the user to enable or disable the device without having to power cycle the system.

The ZR2431N801TA is a great choice for applications that require a low-power, high-accuracy voltage reference. It is widely used in battery management, analog-to-digital converter (ADC) interfacing, microcontroller/microprocessor-based designs and power supplies.
