Analog Devices Inc./Maxim Integrated MAX16060BTE+T

Overview

The MAX16060BTE+T from Maxim Integrated is a 1% accurate quad-voltage microprocessor supervisor in a 16-pin 4mm × 4mm thin QFN package. It monitors four independent supply rails (e.g., 3.3V, adjustable, adjustable, and 1.8V per Table 1), provides open-drain outputs with internal 30µA pullups, asserts RESET on any undervoltage or manual reset event, and includes a 1.6s typical watchdog timer. It serves multivoltage ASIC power sequencing and fault monitoring in industrial servers.

For engineers reviewing the MAX16060BTE+T datasheet, MAX16060BTE+T pinout, MAX16060BTE+T application, or MAX16060BTE+T equivalent, key selection criteria include its 1% threshold accuracy over –40°C to +125°C, capacitor-adjustable reset timeout (min 140ms), tolerance-selectable 5%/10% thresholds, margin-enable function for test-mode deassertion, and guaranteed RESET assertion down to VCC = 1V.

Technical Context

The MAX16060BTE+T implements independent voltage comparators per input (IN1–IN4), each driving a dedicated open-drain output (OUT1–OUT4), plus a wired-OR RESET output that latches low until all monitored voltages exceed thresholds and MR is released. Its reset timeout is set either internally (140ms min) or externally via SRT-to-GND capacitor (t_RP = 2.06 MΩ × C_SRT).

It integrates a watchdog timer with 54s startup delay and 1.6s typical timeout, disabled by leaving WDI floating; TOL selects 5% or 10% threshold tolerance; MARGIN forces all outputs high during margin testing; and all OUT_/RESET outputs support external pullup to ≤5.5V while retaining internal 30µA pullups.

Compared with MAX16060ATE+T, the MAX16060BTE+T provides two adjustable inputs instead of one fixed 2.5V input-enabling broader low-voltage rail coverage-while maintaining identical timing, accuracy, and package. Against TPS3307-33DGNR, it adds a fourth monitor channel, watchdog, margin enable, and 2× tighter threshold tolerance at the cost of higher integration complexity.

FAQ

What voltage thresholds does the MAX16060BTE+T monitor?

Per Table 1 in the datasheet, the MAX16060BTE+T is factory-configured to monitor 3.3V (IN1), adjustable (IN2), adjustable (IN3), and 1.8V (IN4). Adjustable inputs have typical thresholds of 0.394V (TOL = GND) or 0.373V (TOL = VCC), allowing monitoring of rails as low as 0.4V using external resistor dividers. The MAX16060BTE+T does not support 2.5V or other fixed thresholds in this variant.

How is the reset timeout configured on the MAX16060BTE+T?

The MAX16060BTE+T offers two reset timeout options: a minimum fixed timeout of 140ms (achieved by connecting the SRT pin to V_CC), or a user-adjustable timeout set by an external capacitor between SRT and GND. The timeout period follows t_RP = 2.06 MΩ × C_SRT, supporting values from ~0.2ms (100pF) to over 3 seconds (1500pF). This flexibility allows precise alignment with system power-up timing requirements.

Can the MAX16060BTE+T monitor voltages below 1.0V?

Yes - the MAX16060BTE+T supports monitoring of voltages as low as 0.4V using its adjustable inputs (IN2 and IN3). With TOL = GND, the internal threshold is 0.394V (±1%); with TOL = V_CC, it is 0.373V (±1%). By adding an external resistor divider, users can scale higher supply voltages (e.g., 1.2V, 1.0V) down to match these thresholds. The MAX16060BTE+T's 1% accuracy ensures reliable detection even at these low levels.

What is the purpose of the MARGIN pin on the MAX16060BTE+T?

The MARGIN pin on the MAX16060BTE+T is an active-low input that forces all OUT1–OUT4 and RESET outputs into a high-impedance (deasserted) state, regardless of input voltage conditions. This enables safe margin testing - for example, during production burn-in or functional test - where supply voltages are intentionally varied while keeping downstream logic active. The MAX16060BTE+T guarantees a 50µs response time from MARGIN assertion to output deassertion.

Does the MAX16060BTE+T require external pullup resistors for its outputs?

No - the MAX16060BTE+T integrates 30µA internal pullup current sources on all open-drain outputs (OUT1–OUT4 and RESET), eliminating the need for external pullup resistors in standard 3.3V logic interfaces. However, if interfacing with higher-voltage logic (e.g., 5V), an external pullup to that voltage (≤5.5V) overrides the internal pullup, and internal circuitry prevents reverse current flow into V_CC.
