TPS2149IDGN, released by Texas Instruments, is an integrated power distribution switch, load driver, and power-on reset. It is composed of two high-side low-side switches, four integrated voltage supervisors, two high-side power switches, one power-on reset with manual reset and two dual-condition 3.3V/5V digital drivers. It has the following features:

• Integrated high-side and low-side power switches
• Integrated power distribution switch, load driver and power-on reset
• 2.5V to 36V input voltage range with adaptive false turn-on voltage
• 2.85V to 18V output voltage range
• High frequency fixed frequency operation
• Reverse current flow protection
• Fault signal output

TPS2149IDGN is mainly used for the control of power supplied to a system. It is mainly used in the automotive, computing and industrial fields, where it provides a low-voltage power distribution switch, a combined load switch and driver, and a reset signal. It is suitable for a wide range of applications, from basic on/off power management to advanced power sequencing and protection.

The architecture of TPS2149IDGN is designed to provide reliable and low-cost power supplies. It is designed to provide three separate switch control logic, two VDD distribution paths, and four voltage supervisors. These features enable the device to provide easy control of multiple power systems. Each of the two switch control logic blocks can switch up to 36V. The combined load switch and digital driver outputs allow for the control of low-voltage loads. The voltage supervisors are used to indicate when the power supply voltage typically falls below a certain voltage. The fault signal output indicates when a switch is open or a load is shorted.

TPS2149IDGN is designed to provide a wide input voltage range, with adaptive false turn-on voltage, so that it can be used in a variety of applications with different input voltages. It also has a reverse current flow protection feature, which prevents the current flowing in the reverse direction. This feature helps to protect the device from overcurrents and overheating, ensuring a reliable operation. It also features a wide frequency range, so that it can be used in applications that require high frequency switching.

TPS2149IDGN provides a low-voltage distribution switch and driver output suitable for powering a wide range of loads, from basic on/off power management to advanced power sequencing and protection. It is suitable for automotive, computing, and industrial applications, making it a versatile power management solution for a variety of different applications. Its combination of features, such as a wide input voltage range, reverse current flow protection, and fault signal output make it an ideal device for power management and sequencing in a variety of different applications.
