ADPL62083UR44Q+T

Supervisors Overview

The ADPL62083UR44Q+T is a low-power supervisory circuit designed for monitoring system voltages within the 1.02V to 4.8V range using a factory-set reset threshold. It operates with a supply voltage from 1V to 5.5V and features an active-low, open-drain reset output. The device draws a typical supply current of 5μA at 3.6V, with a maximum of 6.8μA over temperature up to +125°C. It includes a typical reset timeout of 300ms and is housed in a compact SOT-23-3 package.

Supervisors Feature Summary

• Factory-set reset threshold options ranging from 1.02V to 4.8V
• Low supply current consumption of 5μA typical at 3.6V
• Active-low open-drain reset output with 300ms typical timeout

Supervisors Applications

• Portable battery-powered equipment
• Wireless communication devices
• Handheld instruments

Supervisors Procurement Notes

Verify the specific reset threshold voltage (4.38V) matches the design requirement, as this variant has a fixed factory-set value. Confirm the SOT-23-3 package compatibility with the PCB footprint. Ensure the operating temperature range of -40°C to +125°C meets environmental specifications. Check that the active-low open-drain output configuration aligns with the downstream logic interface.

Supervisors Selection Notes

Select this component when a fixed, precise reset threshold is required without external resistor networks. The low quiescent current makes it suitable for energy-constrained applications. The single-channel supervision simplifies design compared to multi-voltage monitors. Consider the open-drain output requirement for pull-up resistor implementation in the target circuit architecture.

Supervisors Part Context

This part belongs to the ADPL62083 family of supervisory circuits from Analog Devices. The 'UR44' suffix indicates the specific 4.38V reset threshold option. The '+T' denotes tape-and-reel packaging. These devices are engineered for high reliability in portable electronics where power efficiency and space savings are critical design constraints.

Supervisors Replacement Considerations

Direct substitutes must match the 4.38V threshold and SOT-23-3 package. Verify equivalent supply current and reset timeout characteristics. Cross-reference pinouts to ensure compatibility. Generic supervisors may require external components to achieve similar functionality.
