PMIC - Supervisors : X4003S8IZ-2.7A Application Field and Working Principle

The X4003S8IZ-2.7A is a PicoMOS driver IC part of ON Semiconductor’s PMIC- Supervisors family of products. It is mainly used to drive up to three electromechanical relays with a single chip solution. It is designed to minimize external component count and maximize flexibility. This IC is a low cost, low voltage and flexible device with a very low on-state current and supports a wide input voltage range of 2.7 to 5.5V.

The X4003S8IZ-2.7A PMIC Supervisor utilises a combination of CMOS and Bipolar junction transistor (BJT) technologies. This allows for the device to function across extended ranges of supply voltage and for the device to offer competitive levels of electrical and thermal noise immunity. The X4003S8IZ-2.7A PMIC Supervisor contains three separate drivers, which are each capable of operating independently or in conjunction with one another. Each of these drivers has a standby current of 2mA, a supply voltage range of 2.7 to 5.5V, and a maximum peak current of 0.5A. This makes them suitable for driving medium-current relays, inductive loads, and lamps.

The X4003S8IZ-2.7A PMIC Supervisor can be used to control the operation of up to three relay circuits. It can be used in a variety of applications such as motor control, sensoring, lighting control, and signalling systems. When used for motor control, it can be used to control the operation of multiple brushless DC motors, as well as stepper motors. It can also be used to control the speed and direction of different motors.

The working principle of the X4003S8IZ-2.7A PMIC Supervisor involves the use of a CMOS logic circuit to control the operation of the three drivers. The input logic signals are supplied to the CMOS logic circuit, which then determines which of the drivers is enabled and for how long. The enabled driver then supplies the necessary current to its designated output pin. This current is then used to control the operation of the relay, motor, or light. The CMOS logic circuit allows for the flexible control of the current which enables the PMIC Supervisor to be used in a wide variety of applications.

In addition to the three drivers, the X4003S8IZ-2.7A PMIC Supervisor also contains a number of protection features. It has over-current and thermal protection, as well as a fault reporting signal. This protection reduces the risk of damage to the components as well as reducing the time required for servicing. The X4003S8IZ-2.7A PMIC Supervisor also features a shutdown mode which completely turns off the driver.

The X4003S8IZ-2.7A PMIC Supervisor is an ideal solution for driving up to three electromechanical relays with a single chip solution. It is designed to minimize external component count and maximize flexibility. With its low current requirements, wide input voltage range, and a number of protection features, it can be used in a variety of applications from motor control to lighting control, and from sensing systems to signalling systems.
