Single-channel load switch TPS22918DBVR has configurable rise and quick output discharge periods. The layout, Pinout, datasheet, and other specific details about Texas Instruments’ TPS22918DBVR are primarily covered in this article.

TPS22918DBVR Description

Single-channel load switch TPS22918DBVR has configurable rise and quick output discharge periods. The system contains an N-channel MOSFET that operates between 1 and 5.5 V and has a maximum continuous current handling capacity of 2 A. The switch is controlled directly by low-voltage control signals through an on/off input that can interact with it.

Power supply droop is decreased or completely eliminated thanks to the device’s adjustable rise time; it reduces the inrush current caused by significant bulk load capacitances. The TPS22918DBVR offers design flexibility in terms of power down and sequencing thanks to a programmable quick output discharge (QOD) pin that modifies the device’s fall time.

The TPS22918DBVR is offered in a small, leaded SOT-23 packaging (DBV), making it possible to inspect solder joints visually. The device is made to function in the open air at temperatures between -40°C and +105°C.

What is a load switch?

Simply put, a load switch is a mechanical or electronic switch used to connect or detach a load from the high side of a power supply. A load switch is a wall switch for lighting. A load switch is any on/off switch found on an appliance or electrical equipment. Load switches can be relays.

But a load switch is also a tiny electrical switch employed in many products to set up and control power distribution. Using a fully integrated IC load switch has many benefits over making a load switch out of discrete components.

How Load Switches Work

A MOSFET is the most popular kind of dc load switch. This discrete component switch uses a gate-control MOSFET and a series P-type MOSFET. Typically, a microcontroller’s GPIO output drives the control transistor.

The lower MOSFET is turned on by applying a positive logic level to the enable input (EN), which grounds the gate of the series MOSFET and applies a forward gate-source voltage to turn on the series transistor. To reduce the input voltage drop that happens when the switch is turned on, the capacitor regulates the rise time of the output voltage. Enhancement-mode MOSFETs provide low series on-resistance to reduce voltage loss and power consumption.

Why Do You Need A Load In A Circuit?

Electrical appliances and lights used in the home are examples of electrical loads. An electrical load is a part of a circuit or an electrical component that uses (active) electricity. The term may also refer to a circuit’s power consumption. A power source, like a battery or generator, generates power in contrast to this.

Electrical Load

Any circuit component that uses power or energy is called an electrical load. The most prominent examples of electrical loads in a home are light bulbs and appliances. A load on a circuit is, more broadly speaking, any resistor or electric motor in a circuit that transforms electrical energy into light, heat, or valuable motion. Typically, the resistor symbol represents the load in simplified circuit designs.

A circuit’s load and current flow are inversely related, with larger loads reducing a circuit’s current. However, if there isn’t a big load in a closed circuit, a short circuit will happen and might potentially do a lot of harm.

Why Is It Important To Understand Your Electrical Load?

Understanding your electrical load will help you better comprehend how much energy is used in your home, which is perhaps the most crucial factor. Your electrical load tells you how much energy your appliances and house require to run, which is an excellent indicator of how much energy your house will consume.

You’ll have more control over your monthly power cost if you know the electrical demands of your home’s essential appliances.

If you’re on a demand charge rate, it’s also crucial to understand the electrical load of your appliances and house. A demand charge rate is a tariff established by your utility that bases your costs on the amount of electricity you used when it was the highest. Your maximum power demand can be decreased, and your demand charge-based electric bill can be decreased by controlling the electrical loads used at any given time.
