  • Features low quiescent current consumption.
  • Operates at high efficiency.

Package

The TPS24770RGER is available in a small outline integrated circuit (SOIC) package.

Essence

The essence of the TPS24770RGER lies in its ability to safeguard electronic systems from damaging overvoltage events.

Packaging/Quantity

The TPS24770RGER is typically sold in reels, with each reel containing a specific quantity of ICs. The exact quantity may vary depending on the manufacturer's specifications.

Specifications

  • Input Voltage Range: 2.5V to 18V
  • Overvoltage Threshold Range: 2.7V to 16V
  • Quiescent Current: 10µA (typical)
  • Operating Temperature Range: -40°C to 125°C
  • Package Type: SOIC-8

Detailed Pin Configuration

The TPS24770RGER has the following pin configuration:

  1. EN (Enable)
  2. GND (Ground)
  3. VIN (Input Voltage)
  4. VOUT (Output Voltage)
  5. PG (Power Good)
  6. OV (Overvoltage Threshold)
  7. FB (Feedback)
  8. SS (Soft Start)

Functional Features

  1. Overvoltage Protection: The TPS24770RGER monitors the input voltage and quickly shuts down the output when an overvoltage condition is detected, preventing damage to downstream components.
  2. Adjustable Threshold: The overvoltage threshold can be adjusted to suit specific system requirements, allowing flexibility in setting the desired protection level.
  3. Fast Response Time: The device responds rapidly to overvoltage events, minimizing the duration of exposure to excessive voltage levels.
  4. Power Good Indicator: The PG pin provides a signal indicating whether the output voltage is within the acceptable range, enabling system-level monitoring and fault detection.
  5. Soft Start Function: The SS pin allows for a controlled startup sequence, reducing inrush current and preventing voltage spikes during power-up.

Advantages and Disadvantages

Advantages

  • Provides reliable overvoltage protection for sensitive components.
  • Adjustable threshold and response time offer customization options.
  • Wide input voltage range accommodates various system configurations.
  • Low quiescent current consumption helps conserve power.
  • High efficiency operation minimizes power losses.

Disadvantages

  • May require additional external components for complete system integration.
  • Limited to applications requiring overvoltage protection only.

Working Principles

The TPS24770RGER works by continuously monitoring the input voltage and comparing it to the user-defined overvoltage threshold. When the input voltage exceeds this threshold, the device quickly disables the output to prevent any damage to downstream components. The adjustable threshold and response time allow for customization based on the specific needs of the application.
