S-1132B33-I6T2G, being part of the family of PMIC – Voltage Regulators – Linear, is a stable and advanced accessory for electronic control system. It is designed for low-voltage and low-power applications, mainly for precision-controlled power supply, motor drive or battery management. This article explains its application field, practical implementations and working principle.

The voltage regulator part of S-1132B33-I6T2G is core element of many low-power motion control applications, such as in smooth rotation of Non-overlap motors. This is achieved with soft adaptive voltage coefficient which adjusts the rotational speed. The S-1132B33-I6T2G also has a low on-state resistance (7.5mOhm @Vin=5V), allowing modes of operation such as low-power, high-efficiency regulation, low-ripple stability, peak-load current compatibility, and very low output ripple.

This voltage regulator modifies output voltage, to ensure that it is held steady despite changes in load of the device. This is extremely important for low-voltage and low-power applications, that usually require maintenance of power supply under wide range of ambient temperature and humidity levels, preserving as close as possible constant voltage output. Using the built-in device compensation and implementation of load-balance and load-sharing, S-1132B33-I6T2G ensures protection of the load even at extreme temperatures.

Regarding precision-controlled power supply, S-1132B33-I6T2G can provide a precise current as a reference, according to a power supply datasheet. This is done with the help of built-in control functions, such as voltage control bands and fold-back characteristics. This current can be used for powering microprocessors, logic and memory components, and provide accurate regulation. The precision of this specific component is remarkable, being 5%, 0.4% for line regulation, and 0.4%, 0.2% for load regulation.

For motor drive, the linear voltage regulator provided by S-1132B33-I6T2G is a key component in the circuitry of brushed DC motors. This is done with the help of built-in over-current protection features and thermal shutdown, that ensure the safe operation of electrical elements, protecting them from thermal damages and excessive currents. Also, integrated fault detect and latch functions, along with an internal voltage reference, give it the ability to control the current delivery and protect the motor in case of errors in the recognition. This integral feature of this component makes it highly desirable for motor drive architecture.

On the other hand, S-1132B33-I6T2G is a perfect ally for battery management. The linear regulators are very efficient when it comes to use of the battery for uninterrupted power delivery. This is achieved by the combination of the low-voltage reference, the precision-control capabilities, with the internal over-current protection, and the thermal-shutdown feature. These functions help to deliver high-precision current, preventing battery drain, and maximize its power efficiency. These regulators are also effective in protecting the battery from damage caused by poor current control.

Now that the application field of S-1132B33-I6T2G has been discussed, let’s examine how it works. The linear regulator module works on the principle of comparison of two different voltages. The regulator takes the voltage provided by the power source, and compares it with a reference voltage. If a difference exists, the regulator reduces the voltage to the desired level by dissipating the difference as heat. This structure has been simplified to control functions, such as Over-current protection and thermal shutdown, which help to limit the amount of current and adjust the output voltage, while avoiding excessive heat generation.

In summary, S-1132B33-I6T2G is part of the family of PMIC – Voltage Regulators – Linear, and it is designed for low-voltage and low-power applications. Its application field is wide, and the modular design with built-in device compensation and control functions makes it a desirable partner for many control systems. It works by comparing two voltages and adjusting the output through dissipation of the difference, and giving the device protection from thermal damage and current overload.
