AD8280WASTZ-RL

Overview

The AD8280WASTZ-RL is a six-channel lithium-ion battery safety monitor manufactured by Analog Devices Inc. It operates within an 8 V to 30 V supply range and supports the industrial temperature range of -40 °C to +105 °C. The device features an internal reference and low-dropout regulator powered directly from the cell stack. Each channel includes programmable deglitching circuitry to prevent false alarms from transient inputs. Trip points for overvoltage and undervoltage conditions are established using external resistor dividers in conjunction with the internal reference.

Feature Summary

• Provides independent alarm functions indicating out-of-tolerance voltage conditions without relying on primary monitoring systems.
• Integrates an internal reference and LDO powered completely from the battery cell stack.
• Features programmable deglitching circuitry in each channel to avoid alarming from transient input levels.

Applications

• Lithium-ion battery safety monitoring
• Secondary protection system in battery stacks
• Overvoltage and undervoltage detection

Procurement Notes

Verify component authenticity through authorized channels due to restricted availability status. Confirm package integrity and moisture sensitivity handling requirements before assembly.
