Technical Specifications

Housed in a TO-92-3 through-hole package, this single-voltage supervisor monitors power rails for dips below 4.625V. Upon detecting undervoltage conditions, it asserts an active-low reset signal for at least 250ms after voltage stabilization. The open-drain output supports flexible integration with 3.3V or 5V logic systems. Its wide 1.2V–5.5V operating range makes it suitable for battery-backed and multi-voltage applications.

Typical Applications

• Microprocessor and microcontroller reset circuits
• Industrial control system power monitoring
• Embedded computing and IoT devices
• Automotive electronics subsystems
• Battery-powered equipment voltage supervision

Frequently Asked Questions

Question: What’s the difference between this and voltage detectors?

Answer: Unlike basic detectors, this IC adds a programmable reset timeout period (≥250ms) to ensure stable power before releasing reset.

Question: Can I use this with 3.3V systems?

Answer: Yes, its 1.2V–5.5V operating range supports 3.3V applications while monitoring higher voltage rails.

Question: Does it require external components?

Answer: Typically operates standalone; only requires a pull-up resistor for the open-drain reset output.

Question: Is this suitable for automotive environments?

Answer: With its -40°C to +85°C operating range, it meets requirements for many automotive subsystems.

Question: How does the open-drain output benefit designs?

Answer: Allows flexible voltage level translation and wired-AND connection with other reset sources.

Question: Can I cascade multiple supervisors?

Answer: Yes, open-drain outputs can be paralleled to create multi-voltage monitoring systems.
