The TPS658621DZGUR is a specialized power management integrated circuit (PMIC) for a range of applications in automotive, mobile and embedded solutions.

It is a highly integrated PMIC that integrates a switching regulator controller, voltage tracking, and multiple DC/DC, LDOs and load switches into a single-chip device. This highly integrated PMIC provides a power supply system solution that reduces the external component count and board space, as well as providing a more efficient, low power solution.

The TPS658621DZGUR is designed to provide clean and efficient power conversion for a variety of applications, such as automotive lighting, automotive infotainment, and industrial control systems. It is designed to convert various input supply voltages into a fixed output voltage of 5.0 V and 0.9 - 1.85 V and supports wide input supply voltage range from 4.5 V to 20 V.

The TPS658621DZGUR also supports dynamic voltage and current scaling (DVFS) for applications that require low power consumption and low noise output. The device includes a dedicated voltage tracking pin for controlling the output voltage and a clock gating pin for reducing the current consumption when no output power is required.

The TPS658621DZGUR features a Pulse Automatic Frequency Control (PAFC) to reduce the output voltage ripple and improve the EMC performance. The frequency is controllable from 80kHz to 650kHz and is adjustable through the pulse width. The device also includes a current-limit protection (CLP) circuit to protect the device when there is an overload or over-voltage conditions.

The TPS658621DZGUR also includes an inter-device communication protocol interface that enables communication between multiple devices on a single board and/or multiple boards. The interface supports both I2C and SPI buses, enabling flexible and efficient data transfer, as well as firmware upgrades from a single source.

The TPS658621DZGUR offers a high level of flexibility and system level optimization with integrated power, output current and temperature monitoring, as well as system fault and maintenance features. The device also integrates an over-temperature protection (OTP) circuit, which shuts down the supply if the temperature exceeds a predetermined threshold.

Overall, the TPS658621DZGUR is a specialized PMIC designed for a wide range of applications in automotive, mobile, and embedded solutions. The device provides a cost-effective and highly integrated solution for power supply design, which reduces the component count and streamlines the design process.
