• Introduction

The BAJ0CC0FP-E2 is a linear voltage regulator created to provide stable voltage levels and a wide range of current protection levels for electronic designs and systems. The device is part of the PMIC (Power Management Integrated Circuit) family, with special focus on the Voltage Regulators - Linear category.

• Design Specification

The BAJ0CC0FP-E2 is sampled via a 6-bit amplifier on the input, and then processing is achieved using two stages of voltage regulation. The first stage is a PWM (Pulse Width Modulation) regulator to set the output voltage within the given range, and the second stage is a jitter-compensation circuitry. The device operates from a single 4.5V to 16V supply and supports single output voltages between 2.5V to 7.3V. The maximum output current supported is 2A. The device includes undervoltage lockout circuitry to protect against pulling down the input voltage too low, and also includes overvoltage protection circuitry.The BAJ0CC0FP-E2 also includes a power switch and a logic regulator, which regulate the power efficiency of the load and help protect other components connected to the input. An on-chip sense amplifier enables accurate voltage regulation and overcurrent protection, while slew rate control of the device ensures excellent transient response. Additionally, the device includes a built-in FG (Fault Ground) output that signals when a fault condition occurs.The external components required for the BAJ0CC0FP-E2 are a power inductor, two small ceramic capacitors connected to the input and output, two large polarized electrolytic capacitors, and a pull-up resistor. The device also includes a number of protection features, such as over temperature protection, overcurrent protection, and over voltage protection.

• Applications

The BAJ0CC0FP-E2 can be used in a wide range of applications, including automotive electronics, data communications, medical equipment, consumer electronics and industrial control systems. The device is well-suited for board-level applications, as it requires very few external components, is simple to design, and can be integrated into existing designs without significant modification.The device is particularly useful in automotive electronics applications, where its wide voltage range, accurate voltage regulation, and low profile make it an ideal choice. The device can also be used in medical equipment, consumer electronics and industrial control systems, due to its wide input voltage range and the various protection features included on the device.

• Working Principle

The BAJ0CC0FP-E2 works in two stages to provide voltage regulation. The first stage is a PWM (Pulse Width Modulation) regulator that sets the output voltage within a given range. This stage uses an internal power MOSFET and a control circuit to vary the output voltage according to the desired regulation level.The second stage is a jitter compensation circuitry which is used to fine-tune the output voltage. This circuitry includes a bandpass filter to reject ripple noise and an internal current-sense amplifier which feeds the control circuit of the PWM stage. This circuit also functions as an over-current protection to prevent the device from operating outside its specified current levels. The device also includes a logic regulator to regulate the power efficiency of the load, as well as an on-chip sense amplifier for accurate voltage regulation and overcurrent protection. Additionally, the device includes a built-in FG (fault ground) output that signals when a fault condition occurs.

• Conclusion

The BAJ0CC0FP-E2 is a linear voltage regulator that helps stabilize the output voltage of electronic designs and systems. It is part of the PMIC (Power Management Integrated Circuit) family and its devices are categorized as Voltage Regulators - Linear. The device operates from a single 4.5V to 16V supply and supports single output voltages between 2.5V to 7.3V, with a maximum output current of 2A. It also includes various protection features such as over temperature protection, overcurrent protection, overvoltage protection and undervoltage lockout. The BAJ0CC0FP-E2 can be used in a wide range of applications, including automotive electronics, data communications, medical equipment, consumer electronics and industrial control systems. The device works in two stages to provide voltage regulation, by using an internal PWM regulator, and then a jitter-compensation circuitry to fine-tune the output voltage.
