DS1842N+

Overview

The DS1842N+ is a current and power monitor regulator manufactured by Analog Devices Inc./Maxim Integrated. It features a high-side sensing architecture with a 76V APD bias output stage. The device operates on a supply voltage ranging from 0 V to 11 V, drawing a typical operating supply current of 2 mA. It supports surface-mount installation in a TDFN-EP-14 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a dedicated 76V avalanche photodiode (APD) bias output stage for specialized optical applications.
• Provides high-side current and power monitoring capabilities for precise circuit regulation.
• Utilizes a compact TDFN-EP-14 surface-mount package designed for efficient thermal dissipation.

Applications

• Avalanche photodiode biasing circuits
• Optical communication system power monitoring
• High-voltage current sensing applications

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical characteristics and pinout compatibility before integration. Ensure that the 76V APD bias requirement aligns with the target application design. Confirm RoHS compliance status through official datasheets. Check for any discontinuance notices or lifecycle changes directly from Analog Devices to ensure long-term availability.

Selection Notes

Select this component when a combined high-side current monitor and high-voltage APD bias generator is required. The 11V logic supply allows for easy interface with standard digital controllers. Consider the TDFN-EP-14 footprint for PCB layout constraints. Verify that the 2mA quiescent current meets the system's power budget requirements.
