TPS2091D

TheTPS2091D is a member of TI’s family of Power Management Integrated Circuit (PMIC) solutions that focuses on solutions for power distribution switching, load drive and high current-output applications. The device’s advanced performance, efficiency and programmability make it a great solution for applications requiring power switching.

TheTPS2091D operates with non-isolated, inductive and non-capacitive loads. It contains two PWM outputs that can be used to drive loads. The outputs can be programmed with either on/off or PWM mode. The on/off mode provides discrete control to the load, while the PWM mode provides adjustable frequency and deadtime to the load.

TheTPS2091D also provides a watchdog timer. This feature ensures that the device does not become locked in an unexpected state during normal operation. It also helps to protect the device from being damaged in the event of a fault.

TheTPS2091D features a wide input voltage range from 3.3V to 18V. This makes it suitable for applications requiring high voltage switching or current switching. The device includes programmable fault flags to protect the load in the event of a fault, such as over-current, wrong polarity, or over-temperature. The device also contains a dynamic voltage-ramp feature that allows for smooth transitions between different input voltages, helping to reduce the inrush current and reduce stresses on the power system.

TheTPS2091D features an integrated 1.2A high-side driver and a 0.75A low-side driver. The drivers are capable of delivering a high peak current and have an extended temperature range. The high-side driver can be used to control DC motors and stepper motors, while the low-side driver can be used for a variety of applications such as lighting, lighting control, and motor control.

TheTPS2091D also provides an integrated temperature-monitoring circuit. This circuit monitors temperature within the device and provides both an output signal to the host microcontroller and supplies thermal-protected reset protection. This feature helps to protect the load from being damaged due to abnormal or excessive temperatures.

TheTPS2091D is a highly versatile power management integrated circuit solution. The device offers a robust, integrated solution for both power distribution switching and load drive applications. Its wide input voltage range, VIN, and PWM modes make it ideal for a variety of applications, while its integrated high-side and low-side drivers allow for flexible control of DC motors and lighting applications. The device also features a temperature monitoring circuit and watchdog timer to ensure reliable operation and protection of the load in the event of a fault.
