Product details
Overview
MAX6316LUK29CY from Maxim Integrated is a 5-pin SOT23 microprocessor supervisory circuit with active-low push/pull reset output, 2.93V factory-trimmed reset threshold, 140ms minimum reset timeout, and 1.6s typical watchdog timeout. It monitors VCC supply voltage, provides manual reset input (MR), and asserts reset during power-up, brownout, or software hang - used in portable computers and embedded control systems.
For engineers reviewing the MAX6316LUK29CY datasheet, MAX6316LUK29CY pinout, MAX6316LUK29CY application, or MAX6316LUK29CY equivalent, this page delivers verified specifications, exact pin functions, real-world use cases, and validated alternative parts for industrial and automotive-grade designs requiring guaranteed reset validity down to VCC = 1V.
Technical Context
The MAX6316LUK29CY implements a precision voltage monitor using laser-trimmed resistors to set its 2.93V reset threshold with ±1.5% tolerance at +25°C and ±2.5% over –40°C to +125°C. Its internal reset generator asserts an active-low push/pull RESET signal for ≥140ms after VCC rises above threshold, while the watchdog timer clears on any WDI edge and times out after 1.6s if unserviced.
It integrates MR input with 52kΩ internal pullup and glitch rejection (100ns), supports manual reset assertion with 230ns propagation delay at VCC = 5V, and guarantees valid RESET output down to VCC = 1V - enabling robust operation in battery-powered and automotive environments where supply transients occur.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316MUK29CY-T | Bidirectional active-low RESET output (not push/pull); includes 4.7kΩ internal pullup + active P-FET | Required for Motorola 68HC11-style bidirectional reset buses; not drop-in for push/pull-only designs | Select only when interfacing with μPs needing bidirectional reset arbitration (e.g., legacy HC11-based systems) |
| TLV809E29DBZR | Single-function reset IC; no watchdog or MR input; 2.93V threshold; 200ms reset timeout; SOT23-3 | Lacks WDI and MR functionality; smaller footprint but reduced feature set | Choose when watchdog and manual reset are unnecessary and board space is constrained |
Compared with MAX6316MUK29CY-T, MAX6316LUK29CY offers simpler push/pull drive without bus arbitration complexity; compared with TLV809E29DBZR, it adds critical watchdog and MR features essential for firmware safety-critical systems.

FAQ
What is the reset threshold voltage of MAX6316LUK29CY?
The MAX6316LUK29CY has a factory-trimmed reset threshold of 2.93V, with ±1.5% tolerance at +25°C and ±2.5% over –40°C to +125°C. This value is laser-trimmed during manufacturing and corresponds to the "29" suffix in the part number, matching Table 1 in the datasheet. The threshold ensures precise power-on reset for 3.0V–3.3V digital systems.
Does MAX6316LUK29CY include a watchdog timer?
Yes, MAX6316LUK29CY includes a watchdog timer with a typical timeout period of 1.6s, corresponding to the "Y" suffix in its ordering code. The timer clears on any rising or falling edge at the WDI pin and asserts reset if unserviced for 1.6s. This feature helps detect and recover from firmware hangs in safety-critical applications.
What is the function of the MR pin on MAX6316LUK29CY?
The MR (Manual Reset) pin on MAX6316LUK29CY is an active-low input that forces a reset when pulled low. It features an internal 52kΩ pullup resistor, allowing it to be left unconnected when unused. After MR transitions low-to-high, MAX6316LUK29CY holds RESET asserted for the full 140ms timeout period - enabling hardware-initiated system restarts without CPU involvement.
Is MAX6316LUK29CY compatible with automotive applications?
Yes, MAX6316LUK29CY is rated for –40°C to +125°C operation and is AEC-Q100 qualified, making it suitable for automotive applications. Its guaranteed reset validity down to VCC = 1V, immunity to short negative VCC transients (<4µs), and robust MR/WDI interfaces meet requirements for under-hood and infotainment systems.
What package type does MAX6316LUK29CY use?
MAX6316LUK29CY uses a 5-pin SOT23 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant and lead(Pb)-free compatible. The top-mark "ACDE" identifies this specific variant. Its miniature footprint supports high-density PCB layouts in space-constrained portable and embedded designs.
