Product details
Overview
The MAX17613AATP+T from Analog Devices is a 4.5V–60V adjustable overvoltage, undervoltage, and reverse-voltage protection IC with integrated 130mΩ (typ) FETs, 3A current limiting, and thermal shutdown - designed for industrial sensor power rails and PLC I/O modules requiring robust fault tolerance against ±65V transients.
For engineers reviewing the MAX17613AATP+T datasheet, MAX17613AATP+T pinout, MAX17613AATP+T application, or MAX17613AATP+T equivalent, this device delivers programmable OVLO/UVLO thresholds (5.5–60V / 4.5–59V), reverse-current blocking, startup blanking time control, and real-time current monitoring via SETI pin voltage - critical for high-reliability industrial power sequencing and fault diagnostics.
Technical Context
The MAX17613AATP+T implements dual-NMOS series FET architecture with internal 1.5V reference-based OVLO/UVLO comparators, enabling precise external resistor-programmed trip points. Its current-limit regulation uses closed-loop RON modulation of Q2, with three configurable fault responses: autoretry (1s retry interval), continuous foldback, or latchoff.
Reverse-blocking operation relies on fast (<250ns) detection of VOUT–VIN >105mV (fast threshold) or >11mV (slow threshold), triggering immediate gate drive cutoff. Startup behavior includes 16ms internal UVLO delay after POR and user-programmable TSTART blanking (default 100ms) to accommodate large output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +4.5V to +60V operating; supports -65V negative input tolerance without external TVS |
| Current Limit Range | 0.15A to 3A programmable via SETI-to-GND resistor; ±3.5% accuracy across -40°C to +125°C |
| RON (FET) | 130mΩ typical at 25°C; enables <150mV drop at 1.15A load - critical for low-loss industrial power distribution |
| OVLO/UVLO Adjustment | 5.5–60V OVLO and 4.5–59V UVLO via external resistive dividers; internal fixed 4.2V UVLO backup |
| Reverse Blocking | Active blocking of OUT→IN current; detects VOUT–VIN ≥105mV in <250ns - prevents backfeed in redundant supply systems |
| Operating Temperature | -40°C to +125°C junction range; qualified for extended industrial environments including factory floor and process instrumentation |
| Package | 20-pin TQFN-EP (4mm × 4mm); exposed pad requires thermal vias to GND for 2°C/W θJC performance |
Pinout & Package
Package: 20-pin TQFN-EP (4mm × 4mm), RoHS-compliant, with exposed thermal pad (EP) requiring connection to PCB ground plane via ≥4 thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, IN | High-voltage input supply terminal | Accepts +4.5V to +60V DC; rated for -65V reverse stress; must be decoupled with low-ESR ceramic capacitor |
| 4, UVLO | Undervoltage lockout threshold programming | Connect resistive divider from IN to GND; sets UVLO trip between 4.5V–59V; internal 4.2V default applies if unconnected |
| 5, OVLO | Overvoltage lockout threshold programming | Resistive divider sets OVLO trip between 5.5V–60V; comparator trips at 1.5V internal reference |
| 6, CLMODE | Current-limit fault response mode select | GND = continuous mode; 150kΩ to GND = latchoff; open = autoretry (1s interval after blanking) |
| 7, SETI | Current limit setting & monitoring output | Resistor to GND programs ILIM (0.15–3A); voltage at pin = 1.5V × (ILOAD/ILIM) - enables ADC-based real-time current readback |
| 8, GND | Power and signal reference ground | Must connect to low-impedance system ground; EP pad ties directly to this node for thermal management |
| 9, EN | Enable control input | Active-high logic; internally pulled up to 1.8V; leave open for always-on operation; debounced turn-on prevents false triggering during rail ramp |
| 10, UVOV | Open-drain combined UV/OV fault indicator | Pulled low on UVLO, OVLO, thermal shutdown, or reverse current detection; requires external pullup to system interface voltage |
| 11, FLAG | Open-drain general fault indicator | Asserts low on overcurrent (post-blanking), thermal shutdown, reverse current, or RSETI <1.5kΩ - provides consolidated fault visibility |
| 12, TSTART | Startup blanking time programming | Capacitor to GND sets blanking time (90–110ms default when open); disables current limiting during bulk capacitor charge |
| 13–15, OUT | Protected output supply terminal | Delivers regulated power to load; supports reverse-blocking (MAX17613A only); requires local 4.7µF ceramic output cap |
| 16–20, NC | No-connect pins | Not bonded; must remain unconnected per datasheet - no routing or copper fill allowed |
Key Features
| Feature | Design Value |
|---|---|
| Triple-protection integration | Single-chip solution for OV, UV, and reverse-voltage faults - eliminates need for discrete TVS, Zener, and back-to-back MOSFETs |
| Programmable current-limit response | Three modes (autoretry/latchoff/continuous) allow tailored system recovery strategy without firmware changes |
| Real-time current monitoring | SETI pin outputs 1.5V-referenced analog voltage proportional to load current - enables predictive maintenance and energy logging |
| Hot-plug tolerant design | Operates without external TVS up to 35V input surge - reduces BOM count and board space in modular I/O systems |
| Industrial-grade thermal resilience | Thermal shutdown at 155°C with 15°C hysteresis; 33°C/W θJA on 4-layer board ensures stable operation in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage/overcurrent protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17613BATP+T | Lacks reverse-current blocking; allows bidirectional conduction; identical OV/UV/current-limit specs | Suitable for non-isolated supplies where reverse feed-through is acceptable (e.g., shared bus architectures) | Select when reverse blocking is unnecessary and cost optimization is prioritized - same footprint and pinout |
| TPS26631PWPR | Fixed 4.5–60V OVLO/UVLO; no external resistor programming; 2.5A max current limit; 165mΩ RON | Better suited for cost-sensitive consumer-grade equipment; lacks reverse blocking and SETI current monitoring | Choose for simplified designs without programmability needs - but verify 2.5A limit suffices and accept loss of diagnostic capability |
Compared with MAX17613BATP+T and TPS26631PWPR, the MAX17613AATP+T uniquely combines reverse-current blocking, resistor-programmable thresholds, and analog current monitoring - making it the only option for industrial systems requiring both fault isolation and real-time load telemetry.

FAQ
What protection functions does the MAX17613AATP+T provide?
The MAX17613AATP+T provides adjustable overvoltage protection (5.5V–60V), adjustable undervoltage protection (4.5V–59V), reverse-current blocking (OUT→IN), 0.15A–3A programmable current limiting, thermal shutdown at 155°C, and startup blanking time control. It integrates two series NMOS FETs with 130mΩ typical RON and supports industrial temperature range (-40°C to +125°C).
How is reverse-current protection implemented in the MAX17613AATP+T?
The MAX17613AATP+T detects reverse current by monitoring VOUT–VIN; it triggers fast blocking within 250ns when the differential exceeds 105mV, and slow blocking at 11mV for sustained conditions. This function is exclusive to MAX17613A and MAX17613C variants - MAX17613B does not support reverse blocking.
Can the MAX17613AATP+T monitor real-time load current?
Yes. The SETI pin outputs a voltage proportional to instantaneous load current: VSETI = 1.5V × (ILOAD/ILIM). With a known ILIM set by the external resistor, an ADC can directly compute ILOAD. The current mirror ratio is 3000±30 A/A, enabling accurate telemetry without additional sense resistors.
What are the key timing parameters affecting startup behavior of the MAX17613AATP+T?
The MAX17613AATP+T incorporates three startup-related timings: 16ms internal delay after POR before Q2 turns on, 14.4–17.6ms input debounce window (only at power-up), and user-programmable TSTART blanking (90–110ms default). These ensure reliable turn-on despite noisy supply ramps and prevent false overcurrent trips during bulk capacitor charging.
Is the MAX17613AATP+T pin-compatible with other variants in the MAX17613 family?
Yes - MAX17613AATP+T shares identical 20-pin TQFN-EP package, pinout, and footprint with MAX17613BATP+T and MAX17613CATP+T. However, functional differences exist: only MAX17613A and MAX17613C support reverse blocking; only MAX17613A and MAX17613B provide UVOV/FLAG outputs; MAX17613C uses FWD/REV instead.
