Description and Introduction

Voltage Detector The part HT7050A is manufactured by Holtek. It is a high-performance, low-power CMOS voltage detector with a fixed detection voltage of 5.0V. Key specifications include:  

- **Detection Voltage (Vdet):** 5.0V ±2%  
- **Operating Voltage Range:** 1.5V to 24V  
- **Quiescent Current:** 1.5µA (typical)  
- **Output Type:** Open-drain (requires pull-up resistor)  
- **Temperature Range:** -40°C to +85°C  
- **Package Options:** SOT-23, TO-92  

The HT7050A is commonly used for power monitoring, reset circuits, and battery voltage detection.

Alternative Part Number

  • LM2936Z-5.0 --: Low-dropout 5V linear regulator in TO-92, functionally equivalent to the HT7050A with wide availability and similar dropout performance.
  • MCP1700-5002E/TO --: 5V LDO regulator in TO-92 with very low quiescent current, suitable replacement for HT7050A in low-power applications.
  • LP2950CZ-5.0 --: Classic 5V low-dropout regulator in TO-92 package, pin-compatible and widely used as an alternative to Holtek HT7050A.
