Product details
Overview
MAX16013TT+T from Analog Devices is an ultra-small, low-power overvoltage-protection IC designed to drive two external p-channel MOSFETs (P1 and P2) for reverse-battery and overvoltage protection in high-voltage systems. It operates from 5.5V to 72V, features adjustable overvoltage threshold via SET pin, delivers 2µs max propagation delay, and supports -40°C to +125°C operation in telecom power supplies and multicell battery-stack equipment.
For engineers reviewing the MAX16013TT+T datasheet, MAX16013TT+T pinout, MAX16013TT+T application, or MAX16013TT+T equivalent, key selection considerations include its dual-gate-driver architecture (GATE1/GATE2), 10V gate-enhancement capability for low RDS(on) conduction, latch-off behavior during overvoltage (non-latching, unlike MAX16014), and compatibility with 3mm × 3mm 6-pin TDFN-EP packaging.
Technical Context
The MAX16013TT+T integrates a fast comparator with 2µs propagation delay and internal 1.23V reference to monitor input voltage against a user-adjustable threshold set by an external resistor divider on the SET pin. Its GATE1 output drives P1 for reverse-battery protection with VGS clamped to ~10V across 11V–72V VCC, minimizing forward drop versus diode solutions.
GATE2 controls P2 for overvoltage response: it pulls low to enhance P2 during normal operation and rapidly shorts to VCC to turn off P2 when SET exceeds the internal threshold. Unlike MAX16014, MAX16013TT+T automatically re-enables P2 once VIN falls below the adjusted overvoltage threshold-no power-cycle reset required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - enables direct use in 48V telecom, server rails, and up to 12S Li-ion battery stacks without external regulators. |
| Propagation Delay | 2µs (max) - ensures rapid fault response to transients, critical for protecting downstream DC-DC converters and FPGAs. |
| Overvoltage Threshold | Adjustable via SET pin resistor divider - allows precise trip point setting (e.g., 28V, 40V, 57V) without changing ICs across product variants. |
| GATE1/GATE2 Drive | VGS ≈ 10V (clamped) - guarantees low RDS(on) for external p-MOSFETs while respecting ±20V VGS absolute maximum ratings. |
| Operating Temperature | -40°C to +125°C - fully specified for industrial and automotive under-hood environments without derating. |
| Quiescent Current | 25µA to 40µA (typ. at 48V) - minimizes standby power loss in always-on battery-powered systems. |
| UVLO Threshold | 5.0V (typ.) - prevents erratic operation during brownout or cold-start conditions in high-voltage systems. |
Pinout & Package
MAX16013TT+T is housed in a 3mm × 3mm, 6-pin TDFN-EP package with exposed pad (EP) for thermal dissipation. Pin 1 = VCC, Pin 2 = GND, Pin 3 = GATE2, Pin 4 = SET, Pin 5 = EN, Pin 6 = GATE1. The EP must be soldered to a PCB ground plane for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 5.5V–72V; powers internal circuitry and provides reference for gate-drive clamping. |
| GND | Ground reference | Return path for all internal currents; must be low-impedance connection to EP and system ground. |
| GATE2 | P2 MOSFET gate driver | Drives external p-MOSFET (P2); pulled low to enhance P2, shorted to VCC to disable P2 during overvoltage. |
| SET | Overvoltage threshold adjust | Resistive divider input; sets trip point with ±1.5% accuracy over temperature (based on 1.23V internal reference). |
| EN | Active-high enable | High = normal operation; low = forces GATE2 to VCC (P2 off); internally pulled down to GND. |
| GATE1 | P1 MOSFET gate driver | Drives external p-MOSFET (P1); enhances P1 with ~10V VGS for low-loss reverse-battery protection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent gate drivers | GATE1 controls P1 for reverse-battery isolation; GATE2 controls P2 for overvoltage shutdown-enables single-chip protection of both fault modes. |
| Adjustable overvoltage threshold | Set via external resistor divider on SET pin; supports precise, application-specific trip points without firmware or external comparators. |
| 10V gate-clamp enhancement | Maintains ~10V VGS on P1/P2 across full 11V–72V VCC range-ensures robust conduction while avoiding MOSFET gate oxide stress. |
| Auto-recovery overvoltage response | Turns P2 back on automatically when input voltage drops below threshold-eliminates need for manual reset or power cycling (unlike MAX16014). |
| Ultra-low quiescent current | 25–40µA typical over 5.5V–72V supply range-preserves battery life in always-on industrial sensors and portable equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16014TT+T | Latches P2 off after overvoltage event until VCC power cycle; identical pinout, SET threshold, and GATE1 functionality. | Used where fail-safe lockout is required (e.g., medical devices), not auto-recovery. | Select MAX16014TT+T only if system-level safety mandates manual reset after fault. |
| TPS26631RGER | Integrated 60V eFuse with current limiting, thermal shutdown, and programmable UV/OV thresholds; no external MOSFETs needed. | Better suited for space-constrained designs needing combined overcurrent + overvoltage protection. | Choose TPS26631RGER when current-limiting and fault reporting (FLAG pin) are required alongside OV protection. |
Compared with MAX16014TT+T, MAX16013TT+T offers automatic recovery without power interruption-critical for uninterrupted telecom links. Versus TPS26631RGER, MAX16013TT+T provides lower RDS(on) flexibility (user-selected MOSFETs) and higher voltage tolerance (72V vs. 60V), but requires external FETs and layout attention.

FAQ
What is the primary function of the MAX16013TT+T in a power system?
The MAX16013TT+T serves as a dual-MOSFET overvoltage and reverse-battery protection controller. It drives external p-channel MOSFETs P1 and P2 to block reverse current and disconnect the load during overvoltage events. Its core function is to safeguard downstream circuitry-including DC-DC converters and FPGAs-in 5.5V–72V systems such as telecom power shelves and multicell battery stacks. The MAX16013TT+T achieves this with sub-2µs response and auto-recovery behavior.
How does the SET pin on the MAX16013TT+T determine overvoltage trip point?
The SET pin on the MAX16013TT+T accepts a resistive voltage divider connected between VCC and GND. The internal comparator compares the SET node voltage to a precision 1.23V reference; when SET exceeds this threshold, GATE2 is driven high to turn off P2. For example, a 28V trip uses R1 = 215kΩ and R2 = 10kΩ (SET = VCC × R2/(R1+R2)). The MAX16013TT+T datasheet provides exact formulas and tolerance analysis for ±1.5% trip accuracy over temperature.
What is the difference between MAX16013TT+T and MAX16014TT+T?
The MAX16013TT+T and MAX16014TT+T share identical pinout, SET threshold adjustment, GATE1 functionality, and overvoltage detection circuitry. Their key difference lies in fault recovery: MAX16013TT+T automatically re-enables P2 when input voltage falls below the trip point, while MAX16014TT+T latches P2 off until VCC is power-cycled. This makes MAX16013TT+T suitable for systems requiring uninterrupted operation after transient overvoltage, whereas MAX16014TT+T suits safety-critical applications mandating manual intervention.
Can the MAX16013TT+T be used without external MOSFETs?
No, the MAX16013TT+T cannot operate without external p-channel MOSFETs. It is a gate-driver controller-not an integrated eFuse-and requires external P1 (for reverse-battery protection) and P2 (for overvoltage isolation) connected to GATE1 and GATE2 outputs respectively. The device provides only drive signals and protection logic; current-handling capability, RDS(on), and voltage rating depend entirely on the selected MOSFETs. Using it without external FETs leaves the power path unprotected and risks system damage.
What thermal considerations apply to the MAX16013TT+T's 3mm × 3mm TDFN-EP package?
The MAX16013TT+T's 6-pin TDFN-EP package relies on the exposed pad (EP) for thermal conduction. To maintain junction temperature ≤150°C, the EP must be soldered to a minimum 100mm² copper pour tied to internal/external ground planes. At 72V input and 1A load, power dissipation remains <10mW-so thermal design focuses on MOSFETs, not the MAX16013TT+T itself. However, inadequate EP grounding raises ambient temperature around GATE1/GATE2 drivers, potentially degrading MOSFET switching speed and reliability over time.
