LT3010HMS8E#TRPBF Application Field and Working Principle

The LT3010HMS8E#TRPBF is an adjustable voltage regulator designed for high-side current sensing applications. It is designed to replace discrete components with a low-cost, efficient, small footprint alternative that offers precise voltage regulation. This device offers adjustable output voltage range of 1.25V to 35V and a maximum continuous output current of 150mA. It also includes a power supply supervisor to control power up/down sequencing of multiple power domains, and has a low shutdown current of 0.1uA.

The LT3010HMS8E#TRPBF is a monolithic integrated circuit that includes a programmable output voltage regulator, low-side current sense amplifier, high-side current sense amplifier, and two wide bandwidth voltage followers to reduce external EMI effects. It uses charge pumps to generate the output voltage, and can be configured for a variety of output voltage levels from 1.25V to 35V. Alternatively, the device also features an adjustable voltage regulation range of 2.5V to 12V.

The device features a wide input voltage range of 2V to 60V, making it suitable for a variety of applications including automotive, industrial, and consumer. The output voltage is adjustable in several ways, including external voltage of 2.5V to 12V, external reference voltage of 2V to 6V, and internal current source programmable from 0.1V to 4.3V. Also, the output voltage can be controlled via a voltage divider, making it easy to customize the LT3010HMS8E#TRPBF for specific applications.

The LT3010HMS8E#TRPBF contains two wide bandwidth voltage followers to reduce the external EMI effects. This enables the device to provide excellent line and load regulation over the full input to output voltage operating range. The product also includes a power supply supervisor circuit, which simplifies power sequencing of multiple power domains. The power supply supervisor reduces startup time by sequencing the power rails without requiring any external control signals.

The LT3010HMS8E#TRPBF features an adjustable current sense amplifier, which can be used to measure the current in many applications. This device can sense current in both the low-side and high-side of the application, eliminating the need for a separate high-side current sense amplifier. The current sense amplifier features low offset, wide common-mode range, and integrated 3.2V reference, making it extremely useful for current sensing applications.

The LT3010HMS8E#TRPBF also features a temperature sensing function, which allows it to monitor internal temperature and activate an overtemperature protection feature. This feature improves system stability and reliability by automatically shutting down the device when a potential over temperature condition exists. Additionally, it includes an enable pin, which enables easy power control, and a power on reset circuit, which supports system power-on reset sequencing.

The LT3010HMS8E#TRPBF is a high-performance adjustable voltage regulator, ideal for applications that require precision voltage regulation, low-side current sensing, and a wide input voltage range. It offers adjustable output voltage levels, excellent line and load regulation, and a power supply supervisor for voltage sequencing applications. It also features a temperature sensing function and a power-on reset circuit for improved system reliability and protection.
