Product details
Overview
The MAX16014TT from Maxim Integrated is an ultra-small, low-power overvoltage protection IC designed for high-voltage, high-transient systems. It drives two external p-channel MOSFETs (P1 and P2) to provide reverse-battery protection and overvoltage switching, features a 5.5V–72V supply range, latches GATE2 off after overvoltage trip until power cycle, and operates across –40°C to +125°C in automotive and industrial power rails.
For engineers reviewing the MAX16014TT datasheet, MAX16014TT pinout, MAX16014TT application, or MAX16014TT equivalent, key selection criteria include its latch-off behavior under overvoltage, dual-MOSFET gate drive capability, adjustable overvoltage threshold via SET pin, 2µs propagation delay, and 6-pin TDFN-EP package compatibility with high-temp automotive environments.
Technical Context
The MAX16014TT implements a fast comparator-based overvoltage detection circuit with internal hysteresis (5% standard), UVLO at 4.75V–5.25V, and dedicated gate drivers for two p-channel MOSFETs. Its GATE1 output enables low-drop reverse-battery protection by enhancing P1 with up to 10V VGS, while GATE2 drives P2 to isolate the load during overvoltage events.
Unlike the MAX16013TT, the MAX16014TT incorporates a latch that holds GATE2 high (P2 off) until VCC is fully cycled - eliminating automatic recovery and preventing unsafe reconnection during sustained transients. The SET input accepts an external resistive divider to set the overvoltage threshold between ~6V and 72V, with typical accuracy of ±1.5% over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - supports direct connection to 12V/24V/48V battery stacks and telecom power rails without external regulators. |
| Overvoltage Threshold | Adjustable via SET pin - sets precise trip point using external resistor divider; factory-trimmed reference ensures ±1.5% threshold accuracy. |
| Propagation Delay | 2µs max - enables rapid response to fast-rising transients like automotive load dump (tr > 5ms). |
| GATE2 Latch Behavior | Latched off until VCC power cycle - prevents automatic re-enabling during persistent overvoltage, critical for safety-critical isolation. |
| Operating Temperature | –40°C to +125°C - fully specified for under-hood automotive and industrial control cabinet deployment. |
| Quiescent Current | 25µA typical at 48V - minimizes standby power loss in always-on battery-powered systems. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - exposes thermal pad for enhanced heat dissipation during MOSFET switching. |
Pinout & Package
MAX16014TT uses a 6-pin TDFN-EP (3mm × 3mm) package with exposed thermal pad (EP) connected to GND. 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 | Positive supply input | Accepts 5.5V–72V input; powers internal regulator and gate drivers; requires local 0.1µF bypass to GND. |
| GND | Ground reference | System ground return; EP pad must be soldered to PCB ground plane for thermal and electrical integrity. |
| GATE2 | P2 MOSFET gate driver output | Drives gate of second p-channel MOSFET; pulled high to VCC during overvoltage and latched until power cycle. |
| SET | Overvoltage threshold adjust input | High-impedance node (±100nA); connects to resistor divider to set precise trip voltage between ~6V and 72V. |
| EN | Active-high enable input | Internally pulled down; drive high to activate gate drivers; drive low to force GATE2 high and disable P2. |
| GATE1 | P1 MOSFET gate driver output | Drives gate of first p-channel MOSFET for reverse-battery protection; enhances P1 with ~10V VGS above 11V VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Dual p-channel MOSFET gate drive | Simultaneously controls P1 (reverse-battery protection) and P2 (overvoltage isolation) with independent logic and timing. |
| Latched GATE2 shutdown | Prevents automatic recovery after overvoltage event - requires full VCC power cycle to restore P2 conduction, ensuring safe system reset. |
| Adjustable overvoltage threshold | SET pin allows precise, resistor-programmable trip point from ~6V to 72V with ±1.5% accuracy over temperature and supply. |
| Low quiescent current | 25µA typical at 48V enables use in always-on battery systems without compromising runtime. |
| Robust thermal design | 3mm × 3mm TDFN-EP package with exposed pad supports reliable operation at +125°C ambient in enclosed enclosures. |

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 P2 conduction when voltage falls below threshold. | Suitable for non-safety-critical systems requiring continuous operation after transient clearance. | Select MAX16013TT if automatic recovery is acceptable; MAX16014TT required where hard isolation until manual/system reset is mandated. |
| TPS26631PWPR | Integrated 60V eFuse with current limiting, not dual-MOSFET gate driver; no SET-adjustable threshold. | Provides overcurrent + overvoltage protection but lacks reverse-battery MOSFET drive and programmable trip point. | Choose TPS26631PWPR when combined OCP/OVP is needed and external MOSFET control is unnecessary. |
Compared with MAX16013TT, the MAX16014TT adds mandatory power-cycle reset for fail-safe isolation; compared with TPS26631PWPR, it delivers discrete MOSFET control and precision threshold adjustment - making it optimal for high-reliability, high-voltage rail supervision where architecture mandates hardware-latched shutdown.

FAQ
What is the primary function of the MAX16014TT in a power system?
The MAX16014TT serves as a hardware-based overvoltage and reverse-battery protection controller. It drives two external p-channel MOSFETs - P1 for reverse-polarity blocking and P2 for load isolation during overvoltage events. Its defining feature is the latched GATE2 output, which remains off until the input supply is fully cycled, ensuring fail-safe disconnection in safety-critical applications. This behavior is intrinsic to the MAX16014TT and distinguishes it from other members of the MAX16010–MAX16014 family.
How does the MAX16014TT differ from the MAX16013TT?
The MAX16014TT differs from the MAX16013TT solely in GATE2 behavior during overvoltage recovery: the MAX16014TT latches GATE2 high (P2 off) until VCC is power-cycled, whereas the MAX16013TT automatically re-enables P2 when the input voltage falls below the SET threshold. All other electrical specifications - supply range, propagation delay, SET threshold accuracy, pinout, and thermal performance - are identical between MAX16014TT and MAX16013TT.
Can the MAX16014TT be used without external MOSFETs?
No, the MAX16014TT cannot operate as a standalone protection device - it is a gate driver IC requiring two external p-channel MOSFETs (P1 and P2) to implement reverse-battery and overvoltage protection functions. P1 replaces series diodes to minimize forward voltage drop, while P2 provides active load isolation. The MAX16014TT itself contains no power switches; its outputs (GATE1, GATE2) are logic-level drivers rated for 72V tolerant sinking and 10V sourcing capability.
What is the role of the SET pin on the MAX16014TT?
The SET pin on the MAX16014TT is a high-impedance input (±100nA) used to program the overvoltage trip threshold via an external resistor divider connected between VCC, SET, and GND. The internal reference and comparator compare the SET voltage against a trimmed 1.223V threshold, enabling precise adjustment of the overvoltage limit from approximately 6V up to 72V. The MAX16014TT datasheet provides calculation formulas and example values for common thresholds such as 28V or 40V.
Does the MAX16014TT support operation at 72V input continuously?
Yes, the MAX16014TT is fully specified for continuous operation at 72V VCC across its entire temperature range (–40°C to +125°C). Absolute maximum rating is 80V, and internal regulation ensures stable gate drive and comparator functionality at 72V. However, power dissipation in external P1/P2 MOSFETs must be evaluated separately - the MAX16014TT itself draws only 25µA typical quiescent current at 48V and scales modestly at 72V, per the supply current vs. voltage curve in the datasheet.
