Introduction

PMIC (Power Management Integrated Circuits) is an important component in many electronic products. Power Management ICs are devices which allow the efficient management of the energy consumption of electronic components by controlling the voltage and power delivery. Supervisors are one type of PMIC which monitors the power lines of an electronic device, detects any anomalies or fluctuations in voltage or current, and act as an automatic reset switch. The BD5342FVE-TR is a Supervisory IC designed to protect integrated circuits by providing an active output power on/off when undervoltage or overvoltage situations occur.

BD5342FVE-TR Application Field

The BD5342FVE-TR is specially designed for high integration to support multiple applications. It works at a wide input voltage range from 1.8V to 5.5V, making it suitable for lithium-ion batteries or USB power supplies. With its adjustable thresholds, the BD5342FVE-TR can be used to monitor systems that operate at different voltages, giving the user flexibility. The chip can also detect abnormal temperature conditions, making it suitable for use in safety-critical systems. Moreover, the fast 0.6ms response time ensures efficient power management with accurate and reliable results.

BD5342FVE-TR Working Principle

The BD5342FVE-TR is a Supervisory IC which continuously monitors the input voltage and shuts off the output power when it drops below the programmed threshold or rises above the upper limit. It works by comparing the monitored voltage level to two reference levels set by external resistors, one indicating the lower threshold and the other indicating the higher threshold. When the measured voltage falls below the lower threshold, the IC switches off the output power and when the voltage exceeds the upper limit, the IC switches off the output power again. This prevents permanent damage to the system components.

Conclusion

The BD5342FVE-TR is a Supervisor IC designed to safely protect devices from overvoltage and undervoltage. With its wide input voltage range, adjustable thresholds, fast response time, and temperature detection, the BD5342FVE-TR is the ideal choice for multiple applications that require accurate power management with reliable results.
