Power management integrated circuits (PMIC) are integrated circuits that manage the power of electronic devices. PMICs are required to supply regulated current and voltages to integrated circuits. One type of PMIC is power distribution switches, load drivers, which is available from Texas Instruments. The Texas Instruments TPS22968QDMGTQ1 is a power switch integrated circuit that is designed for use in applications where a compact and efficient power switch is required. This article will discuss the application fields and working principle for the TPS22968QDMGTQ1 power switch.

The main purpose of a power switch integrated circuit is to provide a switching mechanism between power sources and loads. The TPS22968QDMGTQ1 is a single, precision, high-side power switch that is designed to operate over a wide range of voltages and power levels. The TPS22968QDMGTQ1 has an enable pin which controls the switching of the power. This enables the TPS22968QDMGTQ1 to be used in applications where a digital control is needed. The TPS22968QDMGTQ1 has a slew-rate controllable output and an adaptive shoot-through protection feature. The TPS22968QDMGTQ1 has a quiescent current of as low as 1.1µA in standby mode and up to 130mV dropout voltage.

The TPS22968QDMGTQ1 is designed for a wide variety of applications, including power distribution for CPUs, GPUs, graphics cards, mobile processors and other multi-core systems. It can also be used to control low voltage signal paths, such as I2C, SPI, and UART. Additionally, the TPS22968QDMGTQ1 is suitable for controlling multiple voltage rails such as 1.5V, 1.3V, and 1.2V or 3.3V, 2.8V, and 1.8V. The TPS22968QDMGTQ1 is also suitable for controlling power in computing applications with power requirements of up to 25W and bundle sizes up to 48V.

The TPS22968QDMGTQ1 is designed to be used in applications where low pass-through current is required. The integrated circuit includes several features to ensure that the control of the power is performed accurately, effectively and safely. These features include an Under Voltage Lockout (UVLO), an Over Voltage Protection (OVP), a Thermal Shutdown (TSD) and a Short-Circuit Protection (SCP). The UVLO prevents the TPS22968QDMGTQ1 from responding to any enable signals or activate the output switches when the input voltage is less than certain value. The OVP feature protects the TPS22968QDMGTQ1 from over-voltage conditions by halting the enable signal once the voltage exceeds a certain threshold. The TSD feature prevents the TPS22968QDMGTQ1 from becoming too hot which can damage the integrated circuit. Finally, the SCP feature prevents the TPS22968QDMGTQ1 from damaging its output by preventing an excessive current flow.

In summary, the TPS22968QDMGTQ1 is a precision, high-side power switch from Texas Instruments suitable for a wide variety of applications. The TPS22968QDMGTQ1 has a slew-rate controllable output with adaptive shoot-through protection, a low quiescent current, a wide operating voltage range and several features to ensure easy and safe control over the output power. The TPS22968QDMGTQ1 is suitable for powering CPUs, GPUs, graphics cards, mobile processors, and other power demanding solutions, as well as providing control over low voltage signal paths.
