- **Flexible Tracking Modes** – Supports coincident, ratiometric, or offset tracking.  
- **Programmable Slew Rate** – Adjustable via external capacitors.  
- **Wide Input Voltage Range** – Operates from 2.7V to 16.5V.  
- **Power Supply Margining** – Allows testing of power supply tolerance.  
- **Fault Detection** – Monitors power supplies for undervoltage and overvoltage conditions.  
- **Adjustable Sequencing Delay** – Configurable via external resistors.
