  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX707CSA has the following pin configuration:

  1. GND: Ground connection
  2. TRIP: Output signal indicating the monitored voltage has fallen below the threshold
  3. TH: Threshold voltage adjustment pin
  4. VCC: Positive supply voltage input
  5. RESET: Active-low reset input
  6. MR: Manual reset input
  7. NC: No connection
  8. VCC: Positive supply voltage input

Functional Features

  • Monitors the voltage level of a power supply and generates an output signal when it drops below the user-adjustable threshold
  • Provides a manual reset option through the MR pin
  • Offers an active-low reset input for external reset control
  • Low quiescent current consumption ensures minimal power usage

Advantages and Disadvantages

Advantages: - Adjustable threshold voltage allows flexibility in monitoring different power supply levels - Low-power consumption extends battery life in portable applications - Compact SOIC package enables space-saving designs

Disadvantages: - Limited to monitoring voltage levels within the specified range - Requires additional external components for proper operation

Working Principles

The MAX707CSA operates by comparing the input voltage with the user-adjustable threshold voltage. When the input voltage falls below the threshold, the TRIP pin is activated, indicating a low-voltage condition. The MR pin provides a manual reset option, allowing the user to clear the output signal. Additionally, an active-low RESET input can be used for external reset control.

Detailed Application Field Plans

The MAX707CSA finds applications in various fields, including: 1. Battery-powered devices: Monitors battery voltage to prevent damage due to undervoltage conditions. 2. Power supply systems: Ensures stable power delivery by detecting and signaling low-voltage situations. 3. Industrial equipment: Protects sensitive components from voltage drops, preventing malfunctions or data loss. 4. Automotive electronics: Monitors vehicle battery voltage to prevent starting issues or electrical system failures.
