LP87702DRHBRQ1 High Quality New&Original IC Integrated Circuit Electronic Components In Stock

short description:

The LP87702-Q1 helps meet the power management requirements of the latest platforms, particularly in automotive radar and camera and industrial radar  applications. The device contains two step-down DC/DC converters, and a 5-V boost converter to support safety critical applications. The device integrates two voltage monitoring inputs for external power supplies and a window watchdog.
The automatic PWM/PFM (AUTO mode) operation gives high efficiency over a wide output current range for buck converters. The LP87702-Q1 uses remote voltage sensing to compensate IR drop between the converter output and the point-of-load, thus improving the accuracy of the output voltage.

PMIC?

I. What is PMIC
PMIC is the abbreviation of power management IC, the main feature is the high integration degree, the traditional multi-output power supply package in a chip so that the multi-power application scenario has higher efficiency, and smaller size. PMICs are often used in CPU systems, such as set-top box design, intelligent voice speaker design, large industrial control equipment design, etc.
A single PMIC can manage multiple external power supplies, mapping different system requirements to the appropriate regulator output voltage. They can also be used on a variety of processors, system controllers, and end applications, requiring only changes to the relevant register settings or firmware, without the need to redesign a new integrated circuit (IC).

The PMIC market is growing by leaps and bounds because of several current trends. One trend is the consumer's pursuit of wireless mobility, which has created a large demand for small, battery-operated devices and the consequent need for more highly integrated power management solutions.
At the same time, there is a growing demand from consumers and manufacturers for products that are energy efficient and reduce carbon emissions. The global "green" trend has increased the demand for electronic products with efficient power management, making power management a very important and popular feature.

Main Functions

PMIC main functions: [power management, charging control, switching control circuit]

- DC-DC converter
- Low Dropout Voltage Regulator (LDO)
- Battery charger
- Power supply selection
- Dynamic voltage regulation
- Power on/off sequence control for each power supply
- Voltage detection for each power supply
- Temperature detection
- Other functions

The more power supplies the PMIC has, the finer the power supply to the modules of the system, the less the power supply of each module is involved, and therefore the more power saving.
