Ultra-Low-Voltage SC70 Voltage Detectors and µP Reset Circuits The **MAX6834IXRD3+T** is a microprocessor (µP) supervisory circuit manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:
### **Specifications:**
- **Manufacturer:** MAXIM (Analog Devices)
- **Part Number:** MAX6834IXRD3+T
- **Package:** 3-SOT-23
- **Type:** µP Supervisory Circuit
- **Output Type:** Active-Low, Push-Pull
- **Number of Voltages Monitored:** 1
- **Reset Threshold Voltage:** Adjustable or Fixed (specific value depends on variant)
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)
- **Operating Voltage Range:** 1.2V to 5.5V
- **Quiescent Current:** Low (typically 5µA)
- **Operating Temperature Range:** -40°C to +85°C
### **Descriptions:**
- The MAX6834IXRD3+T monitors a µP power supply voltage and provides a reset signal to the µP when the voltage falls below a preset threshold.
- It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.
- Available in a compact **SOT-23-3** package, making it suitable for space-constrained applications.
### **Features:**
- **Low Power Consumption:** Ultra-low quiescent current (5µA typical).
- **Adjustable or Fixed Threshold:** Some variants allow adjustment via external resistors.
- **Manual Reset Input:** Allows external pushbutton reset control (if applicable).
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.
- **Guaranteed Reset Output Valid Down to VCC = 1V.**
- **No External Components Required** (for fixed threshold versions).
- **Hysteresis:** Prevents oscillation near the threshold voltage.
For exact threshold voltages and variant-specific details, refer to the official **MAXIM datasheet**.
