DS1810R-10+T&R-W

PMIC or Power Management Integrated Circuits are essential components used in many aspects of today’s modern electronics. They are used to control the voltage and current levels as well as to provide power supply supervision. One such PMIC is the DS1810R-10+T&R-W, and this article will cover its application field, as well as its working principle and internal structure.

The DS1810R-10+T&R-W PMIC is a monolithic voltage regulator with a low voltage monitor, mosfet driver and precision voltage reference. It is designed to provide an automatic power supply supervision in an embedded system. It is ideal for automotive applications where precise monitoring of a battery’s voltage is critical. It is also suitable for n-channel logic level mosfet switches which are used to drive load devices in low voltage systems.

The application field for the DS1810R-10+T&R-W is broad and includes automotive, industrial, communications and consumer applications. This PMIC provides a precise voltage monitoring with an adjustable reset-delay timer. It is also capable of handling wide input voltage ranges, and can control and protect battery charges. Additionally it is suitable for use in low voltage systems, up to 6V, and has an operating temperature range from -40 to 125°C.

The working principle of the DS1810R-10+T&R-W is fairly simple. When the power is applied to the device, the system will monitor the voltage level and when it exceeds a certain threshold an output signal is activated. This output signal can be used to activate an alarm, or to reset the system. Additionally, the PMIC has an adjustable timer feature, which can be used to prevent false triggering.

The device has a precision voltage reference, which contains a voltage divider to monitor the input voltage. This can be set with external resistors to provide a desired reset threshold. When the voltage reaches this level, a signal is sent to the gate driver, which provides the necessary current to power the on/off switch. The on/off switch is an NMOS transistor connected in series with a Schmitt trigger, which is used to detect the voltage level and determine when to activate the reset. The Schmitt trigger acts as an amplifier, increasing the signal strength so that the external circuitry can detect it.

In addition to the reset function, the DS1810R-10+T&R-W also has a low voltage monitor (LVM), which is used to detect when the battery voltage falls below a certain threshold. When this occurs, the LVM will shut off power to the system until the voltage returns to a safe level. This is a useful feature when using the device in applications where low battery voltage is a concern.

In conclusion, the DS1810R-10+T&R-W is an useful PMIC, which is suitable for applications where precise voltage monitoring and power supply supervision is required. It has an adjustable timer and an LVM to provide additional functionality. Its application field is broad and it is designed to function in a wide range of temperature and voltage levels.
