It integrates a precision voltage reference, a comparator, and a reset generator in an 8-uDFN package measuring 2x2 mm. The reset output is active-low, push-pull, so no external pull-up resistor is needed — it drives the reset input of an MCU, FPGA, or SRAM directly. With a threshold of 2.93 V and a minimum reset timeout of 140 ms, this part monitors a single supply rail and holds the reset output for the timeout period. ## Threshold and timeout — what they mean for the BOM The 2.93 V threshold triggers a reset before the supply falls far enough to cause erratic logic behaviour. The 140 ms minimum reset timeout ensures the processor stays in reset through the worst-case power-up ramp. Because the part monitors only one voltage, it fits designs where a single core rail needs supervision. Multi-rail systems need a companion supervisor or a multi-channel part. ## Package and temperature grade The 8-uDFN (2x2 mm) footprint saves board area but the exposed pad requires a thermal land on the PCB for proper soldering. The -40°C to 85°C range covers industrial, telecom, and outdoor equipment but not full automotive under-hood environments. ## Lifecycle and sourcing The MAX16038LLA29+T is listed as Active on the manufacturer's product status. It is ROHS3 compliant, which covers most global regulatory requirements for lead-free assembly.","metaTitle":"MAX16038LLA29+T Battery Backup Circuit, 2.93V Threshold","metaDescription":"MAX16038LLA29+T battery backup supervisor IC from Analog Devices. 2.93V threshold, 140ms reset timeout, active-low push-pull output. -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Strip","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-WFDFN","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-uDFN (2x2)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.71000","currency":"USD"},{"qty":10,"price":"$6.06300","currency":"USD"},{"qty":25,"price":"$5.78080","currency":"USD"},{"qty":100,"price":"$5.01960","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/72204a0ba9425e377aed8f976c699a84.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for the MAX16038?","answer":"The reset timeout is a minimum of 140 ms, ensuring the processor stays in reset long enough for the supply to stabilise after a power-up or brownout event."},{"question":"Is the MAX16038LLA29+T an active-low reset?","answer":"Yes, the reset output is active low, and the output stage is push-pull (totem pole), so no external pull-up resistor is required."},{"question":"What is the MAX16038LLA29+T used for?","answer":"It is a battery backup circuit that monitors a single 3.3 V supply rail and switches to a backup battery when the primary voltage drops below 2.93 V.
