The IMP706ESA is a microprocessor supervisory circuit manufactured by IMP (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features:

Manufacturer:

IMP (Integrated Micropower Electronics)

Part Number:

IMP706ESA

Description:

The IMP706ESA is a precision voltage monitor designed to provide reliable power supply supervision for microprocessor and digital systems. It ensures proper system operation by monitoring power supply voltages and generating reset signals during power-up, power-down, or brownout conditions.

Key Features:

• Voltage Monitoring: Monitors 5V, 3.3V, or adjustable voltage supplies.
• Reset Output: Active-low reset signal (RESET) with a 200ms minimum delay.
• Manual Reset Input: Allows external push-button reset control (MR).
• Watchdog Timer: Independent watchdog timer with a 1.6-second timeout period.
• Power-Fail Comparator: Provides early warning of power failure (PFI/PFO).
• Low Quiescent Current: Typically 35μA for power efficiency.
• Operating Voltage Range: 1.0V to 5.5V.
• Temperature Range: Industrial (-40°C to +85°C).
• Package: 8-pin SOIC (Small Outline Integrated Circuit).

Applications:

• Microprocessor and microcontroller-based systems.
• Embedded controllers.
• Industrial and automotive electronics.
• Battery-powered devices.

Pin Configuration (8-Pin SOIC):

1. PFI – Power-Fail Input

2. PFO – Power-Fail Output (open drain)

3. GND – Ground

4. MR – Manual Reset Input (active low)

5. VCC – Power Supply Input

6. NC – No Connect

7. RESET – Reset Output (active low)

8. WDI – Watchdog Timer Input
