71M6403-IGTR/F Application Field and Working Principle

The 71M6403-IGTR/F is a power management IC (Integrated Circuit) used in a wide range ofapplications such as portable electronics, mobile phones, tablets, wearables, and otherembedded devices. The model is designed by ROHM and is a low voltage type Auto Shut-Off(ASO) DC (Direct Current) / DC converter. The design of this IC is to reduce the quiescent(idle) current, hence, helping to improve the operating time of the equipment while usingthe same battery. Below is a comprehensive overview of this product\'s specifications,application fields, and working principles.

Specifications

The 71M6403-IGTR/F model has a wide operating temperature range from -40 to +85degrees Celsius, voltage between 4.5 and 46 V, supply current between 170 and 182 uA, andoutput current of up to 100 mA. The primary features of this product are also its small packagesize and modularized power solution with integrated power FET (Field Effect Transistor), ashutdown/active switch to control the functionality, and a startup circuit that engages thepower based on an external resistor. Additionally, the model offers reverse current protectionand monitors the output voltage, preventing fluctuations that may cause damage.

Application Fields

As one of the top power management ICs, the 71M6403-IGTR/F is used in a wide range ofapplications including:

• Portable electronics such as digital cameras, portable media players, and other handheld devices.
• Mobile phones, tablets, services, and other embedded communication devices.
• Computer peripherals like keyboards, mice, printers, scanners.
• Wearable electronics including watches, fitness bands, smart clothes.
• Other battery-operated devices like electric vehicles and medical/industrial instruments.

Working Principles

The 71M6403-IGTR/F IC is a low voltage type Auto Shut-Off (ASO) DC/DC converter, whichcan be used to reduce quiescent current. This helps to extend the operating time of theequipment while using the same battery. It is also used to protect the equipment from currentoverload, reverse current, and overvoltage, and to increase efficiency.

In terms of its basic operations, the product works as follows: when an external powersupply is applied to the input electrodes, the voltage entering the IC is detected. If the voltageis within the acceptable range, then the voltage regulator activates and the output voltage isfixed at the desired level. However, if the input voltage is above 46V, then the input stageauto-shutoff circuit (ASO) is activated and the IC is cut off from the input power. The outputvoltage is then maintained at the same level until the input power is restored.

The IC also contains a startup circuit. This circuit monitors for the voltage on the outputelectrodes. When the output voltage is lower than an external resistor, the power FET isactivated and the circuit starts to draw power from the battery. When the output voltagereaches the voltage on the external resistor, the power FET is off, and the circuit returns toan idle state.

Conclusion

The 71M6403-IGTR/F is a low voltage auto shut-off DC/DC converter designed by ROHM withmodularized power solution and integrated power FET. It helps to reduce quiescent currentwhich in turn extends the operating time of the equipment. This IC is a highly reliable andcost-effective power solution and can be used in a range of applications such as portableelectronics, mobile phones, tablets, wearables, and other battery-operated devices.
