Functional description

The VPM2SM is intended to supervise and manage multiple supply rails in modern systems. Each monitored rail has a dedicated comparator with programmable thresholds. When any rail falls outside its configured window, the module asserts an interrupt and can drive a power-good or reset output depending on configuration.

The device integrates a precision reference and ADC channel allowing system firmware to read exact voltages and make higher-level power-management decisions. A small state-machine inside the VPM2SM handles power sequencing: enabling or disabling outputs in a configurable order with adjustable inter-step delays to ensure safe startup/shutdown of dependent subsystems.

Modes:

• Autonomous mode: The VPM2SM controls sequencing and resets based on internal configuration registers without host intervention.
• Host-managed mode: The host MCU configures thresholds and sequencing, and uses control lines (EN, RST) to command transitions.
• Mixed mode: Host sets nominal policy; VPM2SM enforces safety rules (e.g., shut down if undervoltage persists).

Protection features include glitch filtering on inputs, brown-out detection, programmable debounce for transient events, and latchable fault reporting to preserve root-cause data across resets.

Example Component Values (Vishay Suggestion):

• Amplifier: OPA380 or TLV2772 (high bandwidth)
• Feedback Resistor: 10kΩ to 1MΩ (depending on required gain)
• Compensation Capacitor: 2pF to 5pF (to prevent oscillation)

2. Electrical Characteristics

Pin descriptions (example 12-pin UDFN)

• INT — Interrupt output (open-drain) (Actual pinouts vary by package; consult vendor-specific pin map.)

4. Environmental & Mechanical

• Operating Temperature: Wide operating range, typically -40°C to +85°C (ambient). Derating may apply above 50°C or 70°C depending on airflow.
• Cooling: Conduction cooling via the metal case (baseplate) or forced air cooling.

2.2 Output Performance

The output is tightly regulated, capable of delivering high current with minimal ripple.

• Regulation: ±1% typical line and load regulation.
• Ripple and Noise: High-frequency switching noise is minimized, usually below 1% $V_out$ peak-to-peak, reducing the need for bulky external filtering.
