Product details
Overview
The MAX16014TT+ from Analog Devices is an ultra-small, low-power overvoltage-protection IC designed to drive two external p-channel MOSFETs (P1 and P2) in high-voltage systems. It operates from 5.5V to 72V, features adjustable overvoltage threshold via SET pin, latches GATE2 off after overvoltage trip until power cycle, and delivers fast 2μs propagation delay. It is used in telecom 48V power rails and multicell battery-stack protection.
For engineers reviewing the MAX16014TT+ datasheet, MAX16014TT+ pinout, MAX16014TT+ application, or MAX16014TT+ equivalent, key selection considerations include its latch-off behavior on overvoltage fault, dual-MOSFET gate-drive capability (GATE1/GATE2), -40°C to +125°C operation, 6-pin TDFN package, and compatibility with reverse-battery and overvoltage-switch topologies.
Technical Context
The MAX16014TT+ integrates a precision voltage comparator with internal 1.245V threshold (±0.015V), hysteresis selectable at 5% (standard for this variant), and UVLO at 5.0V. Its GATE1 output drives P1 for low-drop reverse-battery protection, while GATE2 drives P2 and latches off during overvoltage - requiring full VCC power cycle to reset.
It uses BiCMOS process technology and supports external resistive divider programming of overvoltage trip point via SET pin. The device asserts no output pins - all control is delivered through GATE1 and GATE2 outputs, each capable of sinking 75µA and clamping to VCC during fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - enables direct use across telecom 48V, server 12V–54V, and 12–60-cell Li-ion stacks without external regulators. |
| Overvoltage Threshold | Adjustable via SET pin resistor divider - allows precise trip points (e.g., 28V, 40V, 60V) tailored to system requirements. |
| Propagation Delay | 2µs max - ensures rapid response to transients, critical for protecting downstream DC-DC converters and FPGAs. |
| GATE2 Latch Behavior | Latches off until VCC power cycle - eliminates automatic retry during sustained overvoltage, enhancing safety-critical isolation. |
| Operating Temperature | -40°C to +125°C - fully specified for industrial and telecom equipment operating in uncontrolled ambient environments. |
| Quiescent Current | 25–40µA at VCC = 48V - minimizes standby power loss in always-on battery-backed systems. |
| Threshold Hysteresis | 5% - provides noise immunity against supply ripple near trip point, preventing false triggering in noisy 48V telecom rails. |
Pinout & Package
MAX16014TT+ is housed in a 3mm × 3mm, 6-pin TDFN-EP package with exposed pad (EP) connected to GND for thermal and EMI performance. Pin 1 is VCC; Pin 2 is GND; Pin 3 is GATE2; Pin 4 is SET; Pin 5 is EN; Pin 6 is GATE1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | Accepts 5.5V–72V; powers internal circuitry and defines GATE1/GATE2 clamp level; requires ≥0.1µF bypass to GND. |
| GND (Pin 2) | Ground reference | Common return for all signals and EP; must be low-impedance connection to minimize ground bounce during MOSFET switching. |
| GATE2 (Pin 3) | P2 MOSFET gate driver | Drives external p-channel MOSFET (P2); pulled to VCC during overvoltage to turn P2 OFF; latched OFF until VCC power cycle. |
| SET (Pin 4) | Overvoltage threshold adjust | Connects to resistive divider from VCC to GND; sets trip voltage using internal 1.245V reference; high-impedance input (<100nA). |
| EN (Pin 5) | Active-high enable | Drive high to activate protection logic; drive low to force GATE2 = VCC (P2 OFF); internally pulled down to GND. |
| GATE1 (Pin 6) | P1 MOSFET gate driver | Drives external p-channel MOSFET (P1); enhances P1 with ~10V VGS for low RDS(on); eliminates series diode drop in reverse-battery path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual p-channel MOSFET gate drive | GATE1 controls reverse-battery MOSFET (P1); GATE2 controls overvoltage-isolation MOSFET (P2) - enabling single-chip bidirectional protection. |
| Power-cycle-latched overvoltage shutdown | GATE2 remains latched at VCC until VCC is fully cycled - prevents unsafe auto-recovery during persistent overvoltage faults. |
| Adjustable overvoltage threshold | SET pin accepts standard resistor dividers to set trip point from ~6V to >70V - eliminates need for external comparators or DACs. |
| Low quiescent current | 25–40µA across 48V supply - extends battery life in portable telecom equipment and remote sensors. |
| High-temperature operation | Guaranteed functionality from -40°C to +125°C - suitable for enclosed industrial enclosures and base station power modules. |
Applications
| 48V Telecom Power Rail Protection | Notebook Computer Battery Stack Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16013TT+ | No GATE2 latch - automatically recovers when voltage falls below threshold. | Suitable for non-safety-critical overvoltage limiting where auto-retry is acceptable. | Select MAX16013TT+ only if system design permits automatic re-engagement after overvoltage clears. |
| TPS26631RGER | Integrated 60V eFuse with current limiting, not dual-MOSFET gate driver; no SET-adjustable threshold. | Used for overcurrent + overvoltage combo protection; lacks reverse-battery MOSFET drive (GATE1). | Choose TPS26631RGER when precise current limiting and integrated FETs are prioritized over adjustable OV threshold and discrete MOSFET flexibility. |
Compared with MAX16013TT+, the MAX16014TT+ adds mandatory power-cycle reset for fail-safe isolation; compared with TPS26631RGER, it offers programmable OV threshold and independent control of two external MOSFETs - essential for high-efficiency reverse-battery + overvoltage architectures.

FAQ
What is the function of the SET pin on the MAX16014TT+?
The SET pin on the MAX16014TT+ serves as the overvoltage threshold adjustment input. It connects to an external resistor divider between VCC and GND, allowing precise programming of the trip voltage using the device's internal 1.245V reference. For example, a 100kΩ–200kΩ divider can set thresholds from 12V to 60V. The MAX16014TT+ uses 5% hysteresis, ensuring stable operation near the trip point in noisy telecom environments.
How does the MAX16014TT+ differ from the MAX16013TT+ in overvoltage response?
The MAX16014TT+ differs from the MAX16013TT+ by latching GATE2 OFF after an overvoltage event until the VCC supply is fully cycled, whereas the MAX16013TT+ automatically resumes normal operation once the input voltage drops below the threshold. This latch behavior makes the MAX16014TT+ suitable for safety-critical applications where unintended re-engagement during sustained overvoltage could damage downstream loads.
Can the MAX16014TT+ drive both P1 and P2 MOSFETs simultaneously during normal operation?
Yes, the MAX16014TT+ drives both P1 and P2 MOSFETs simultaneously during normal operation: GATE1 enhances P1 to provide low-drop reverse-battery protection, while GATE2 enhances P2 to maintain low-RDS(on) conduction. Both outputs operate with ~10V gate drive for VCC > 11V, ensuring minimal forward voltage drop and high efficiency - critical in battery-powered telecom and notebook systems.
What is the maximum continuous supply voltage the MAX16014TT+ can withstand on the VCC pin?
The MAX16014TT+ supports a continuous supply voltage range of 5.5V to 72V on the VCC pin, with absolute maximum rating of +80V. This 72V operational limit enables direct integration into 48V telecom systems, 60-cell Li-ion battery stacks, and industrial 24V/48V power rails without external voltage clamping - provided transient suppression (e.g., TVS) is added per application note guidance for >72V spikes.
Does the MAX16014TT+ include internal undervoltage lockout (UVLO), and what is its threshold?
Yes, the MAX16014TT+ includes internal undervoltage lockout (UVLO) with a nominal threshold of 5.0V (range 4.75V to 5.25V). When VCC rises below this threshold, GATE2 is forced high (disconnecting P2), and the device remains inactive until VCC exceeds UVLO. This prevents erratic operation during power-up or brownout conditions - a key reliability feature in server and industrial power systems.
