PMIC - Supervisors: BD4827FVE-TR Application Field and Working Principle

The BD4827FVE-TR is a quad system supervisor IC with reset/power-on reset function from ROHM Semiconductor. It is designed for use as a supervisor IC in watching digital and Analog systems and peripheral circuits for home appliances and computer systems, which are supervised by a single power supply.

Application Fields

The BD4827FVE-TR is a fully integrated supervisor IC designed for use in digital and analog system watching applications including computer systems and peripheral circuits, home appliances, and industrial components. The application fields can be summarized as:

  • Computer Systems
  • Peripheral Circuits
  • Home Appliances
  • Industrial Components

Working Principle

The BD4827FVE-TR offers 4 independent supervisors with a reset, power-on reset, power-fail reset input, and reset output. It also includes reset voltage detectors, flip-flop, OR circuits, and open-drain FETs, which are used to generate reset/ power-on reset outputs. When any one of the reset/ power-on reset inputs is low, the watchdog reset output is triggered. Additionally, when an input power supply is applied to VCC and the power-on reset input is low, the power-on reset output is triggered.

In addition to the reset/power-on reset functions, the BD4827FVE-TR integrates a reset voltage detector (RVD) to monitor the power supply connected to VCC. Whenever the voltage level from VCC drops below the factory-set threshold, the circuit trips the reset output when the WDI pin goes low. The reset output will be held low for the length of the external reset pulse, after which the circuit is reset, triggering a reset output. The watchdog timer (WDT) on the BD4827FVE-TR is set as a 1-second timer featuring either an umbral or an integrated reset.

Pin Assignments

The BD4827FVE-TR has an 8-pin package composed of:

  • VCC (power supply voltage)
  • GND (ground)
  • WDI (watchdog input)
  • WDO (watchdog output)
  • RST1/RST2 (reset inputs)
  • PON1/PON2 (power-on reset inputs)
  • RESET (reset output)

The VCC and GND pins are the power supply voltage and ground pins respectively and the RST1/RST2, PON1/PON2, and WDI pins are the reset/power-on reset inputs. The WDO pin is the watchdog output, and RESET pin is the reset output. The BD4827FVE-TR allows for the microcontroller to be reset when the power supply voltage drops below a certain voltage level or when one of the reset/power-on reset inputs is low.

Summary

The BD4827FVE-TR is a quad system supervisor IC with reset/power-on reset functions. It is designed for use in the application fields of computer systems, peripheral circuits, home appliances, and industrial components and offers 4 independent supervisors with reset, power-on reset and power-fail reset inputs and reset output. The 8-pin package includes a VCC power supply voltage, GND ground, WDI watchdog input, WDO watchdog output, RST1/RST2 reset inputs, PON1/PON2 power-on reset inputs, and RESET reset output. The BD4827FVE-TR has a reset voltage detector (RVD), flip-flop, OR circuits, and open-drain FETs, which are used to generate reset/power-on reset outputs. Furthermore, the design integrates a watchdog timer which is set as a 1-second timer featuring either an umbral or an integrated reset.
