It is designed to drive a Peltier element for precise temperature control in laser diode modules, optical transceivers, and medical diagnostic equipment where sub-degree thermal stability is required. ## Package and thermal interface The 28-TSSOP package with an exposed pad (28-TSSOP-EP) is the key thermal and electrical interface. The 0.173-inch body width (4.40 mm) is standard for TSSOP-28, so existing footprints for the MAX1968 or MAX1978 family are a direct layout match. Supplied in tube packaging, not tape-and-reel — a detail that matters for pick-and-place setup if your assembly house expects reeled parts. The tube quantity is typically 50 or 74 units per tube depending on the supplier's packing standard; confirm the tube count at RFQ to avoid a line-stop. It is ROHS3 compliant, so it passes EU RoHS directives without exemption declarations. For new designs, this part is a safe BOM choice; no near-term obsolescence risk.","metaTitle":"MAX1969EUI+ TEC Driver IC, 3V-5.5V, 28-TSSOP-EP","metaDescription":"MAX1969EUI+ thermoelectric cooler driver from Analog Devices.

The output current polarity reverses to heat or cool the TEC. A typical application uses a thermistor feedback loop to the controller input for closed-loop temperature stabilization."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1969EUI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1969EUI when reusing this data.
