LTC2952IUF#TRPBF are Power Supply Controllers, Monitors (PMICs) designed specifically for industrial control applications and applications operating in harsh environments. These devices provide accurate control and monitoring of power supply rail voltages in industrial and consumer applications.

The LTC2952IUF#TRPBF PMICs are assembled with high-side current sense amplifiers and incorporate a non-volatile portion of the controller which works as a configurable Trip Level Threshold (TLT) that allows varying threshold levels to be configured. This feature enables the LTC2952IUF#TRPBF PMIC to protect against current overloads and over-voltage situations.

The LTC2952IUF#TRPBF PMICs have a wide input voltage range of 4.5V to 18V and can deliver up to 3A of continuous output current. These PMICs work by monitoring the voltage on the power supply rail and maintaining the rail level within a certain tolerance range. The LTC2952IUF#TRPBF PMICs use a high side current sense amplifier to detect any over-current situation and shut off the power supply by turning off the supply rail if a preset level is exceeded.

The LTC2952IUF#TRPBF PMICs provide a fully integrated power solution for industrial applications and can also be used for AC/DC or DC/DC applications. It is composed of a Bootstrap bias circuit to supply the Gate Drive VGS necessary for the N-channel MOSFET, an adaptive oscillator to determine the switching frequency, a Error amplifier to regulate the output voltage, and a thermal shutdown circuit to prevent overheating. Additionally, the LTC2952IUF#TRPBF PMICs feature a built-in reset circuit that monitors the output voltage and automatically resets the PMIC after power-up.

The LTC2952IUF#TRPBF PMICs are designed to operate over a wide temperature range of -40°C to 125°C with an operating frequency of between 0.9MHz and 1.1MHz. This ensures safe and reliable operation under extended temperature or overloaded conditions. These devices also feature internal loop compensation and transient immunity for improved performance during phase-shift and load-step operations. The combination of adjustable over-current and over-voltage protection and wide temperature range makes these devices an ideal choice for industrial and consumer applications.

In summary, the LTC2952IUF#TRPBF PMICs provide an integrated power solution for industrial applications. These PMICs offer wide operating frequency range, thermal and over-current shut-off, adjustable Trip Level Threshold, reset circuit, loop compensation, and transient immunity. All these features make these devices an excellent choice for industrial and consumer applications operating in harsh environments.
