RT9819G-29GV

The RT9819G-29GV is an integrated power management IC (PMIC) that is capable of providing up to 900mA maximum output current for different loads commonly found in consumer and industrial applications. The RT9819G-29GV is mainly divided into two categories, supervisors and regulators. It is mainly used for monitoring overall system, power monitoring and regulation, and providing over-current protection.

RT9819G-29GV Application Field

One of the main application fields of the RT9819G-29GV is consumer applications. The high maximum output current and the adjustable voltage levels make it ideal for powering several consumer products. It also provides thermal protection, over-voltage, and over-current protection, making it suitable for use in many safety-critical applications such as in medical and industrial environments. In addition to these applications, it is widely used in automotive, telecommunications and computer applications due to its excellent electromagnetic interference (EMI) performance. The low quiescent current of the RT9819G-29GV makes it a good choice for portable and battery-powered systems.

RT9819G-29GV Working Principle

The RT9819G-29GV is a supervisor PMIC. It provides over-current protection, two power supply pins, a reset pin and a manual reset circuit. The reset pin is used to output a reset signal when the system voltage drops below the threshold level. The manual reset circuit is used to reset the system manually in case the reset pin is not accessible. The two power supply pins are used to supply power to the monitoring circuitry. The RT9819G-29GV monitors the input voltage and the output current to protect the system from over-current and over-voltage conditions.

The RT9819G-29GV can be used to monitor the supply voltage, the output current and the temperature. The supply voltage is monitored using the inputs at VIN0 and VIN1. The output current is monitored using a sense resistor R_SENSE. The temperature is monitored by measuring the die temperature. When the supply voltage, output current or die temperature exceed their thresholds, the RT9819G-29GV will issue a system reset signal to protect the system.

The RT9819G-29GV is a highly integrated and modular power management IC with an excellent thermal performance and protection features. It is suitable for providing power to a wide range of consumer and industrial products. The adjustable voltage level and the over-current, over-voltage, and temperature protection features make the RT9819G-29GV an ideal choice for many safety-critical applications.
