Power management integrated circuits (PMICs) are digital devices that are designed to consolidate and enable the efficient utilization of the power functions prevalent in a digital system, by handling the power switches, voltage distributions and current regulation function that are required to keep power systems operating. Typically they are used to control the power supply in devices such as cell phones, tablets, gaming devices and wearables. The LTC1559CGN-3.3#TRPBF is a member of Linear Technology’s family of PMICs and has been specifically designed for battery management applications.

Features and Benefits

The LTC1559CGN-3.3#TRPBF is a 3.3V dual power supply supervisor with advanced features integrated into the device. The device supports an active-high reset output, which is active when the voltage across an external resistor divider falls below a preset threshold. The device can be configured to support a variety of reset levels, allowing it to be used in a wide range of battery chemistries. It also features an MR pin, which is an active-high logic input, that can be used to decrease or increase the reset threshold. This feature is ideal for battery-backed designs, where the MR pin can be used to configure the reset threshold to a lower voltage when the battery voltage is high and then to a higher voltage when the battery voltage is low. The device also has built-in overvoltage and undervoltage protection and a delay time setting to ensure that the device has enough time to respond to conditions that could cause a false reset or power down.

Application Field and Working Principle

The LTC1559CGN-3.3#TRPBF is ideal for a wide range of applications, including portable and battery-backed products, such as handheld games, laptops and cellular phones. It is suitable for battery-fed designs and for applications that require wide input voltage range and low quiescent current. The LTC1559CGN-3.3#TRPBF utilizes a resistor divider to sense the battery voltage level. Once the voltage drops below the preset threshold, the LTC1559CGN-3.3#TRPBF will actuate its reset and shut down the system. It also features a variable reset delay which will allow it to respond more quickly to changing conditions, preventing a false reset or shutdown from occurring.

Conclusion

The LTC1559CGN-3.3#TRPBF is a highly featured, low power consumption power management integrated circuit (PMIC) that is designed for battery management applications. It features an adjustable reset threshold, overvoltage and undervoltage protection, and an adjustable delay time. It is suitable for a wide range of applications, and is ideal for battery-backed products such as handheld games, laptops, and cellular phones.
