SUPPLY VOLTAGE SUPERVISORS The **TL7702ACD1/A** is a voltage supervisor and reset IC manufactured by **STMicroelectronics (ST)**. Below are its specifications, descriptions, and features based on factual data:
### **Specifications:**
- **Manufacturer:** STMicroelectronics
- **Type:** Voltage Supervisor / Reset IC
- **Package:** SOIC-8
- **Operating Voltage Range:** 1.2V to 10V
- **Reset Threshold Voltage:** Adjustable or fixed (depends on variant)

### **Descriptions:**
- The **TL7702ACD1/A** is designed to monitor power supply voltages and generate a reset signal if the voltage falls below a predefined threshold.
- It ensures proper system initialization by holding the microcontroller or processor in reset until the supply voltage stabilizes.
- The reset output can be configured as active-low (typically used for system reset signals).
- It includes an internal delay timer to prevent false resets during power-up or transient conditions.
### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset generation at specified thresholds.
- **Adjustable Reset Delay:** External capacitor allows customization of reset pulse width.
- **Low Power Consumption:** Suitable for battery-powered applications.
- **Wide Operating Voltage Range:** Supports monitoring from 1.2V up to 10V.
- **Robust Design:** Resistant to voltage transients and noise.
- **Open-Drain or Push-Pull Output:** Depending on variant, supports different interfacing needs.
- **Industrial Temperature Range:** Operates reliably in harsh environments (-40°C to +85°C).
