Product details

Overview

MAX17610ATC+ from Maxim Integrated is a robust, adjustable overvoltage, undervoltage, and reverse-current protection IC for industrial power rails. It features dual internal MOSFETs with 260mΩ (typ) total R_ON, programmable current limiting from 0.1A to 1.0A (±3% accuracy above 0.2A), reverse-current blocking down to 11mV threshold, and operates across –40°C to +125°C. It protects sensor systems and PLC modules against ±65V input faults while enabling precise current monitoring via the SETI pin.

For engineers reviewing the MAX17610ATC+ datasheet, MAX17610ATC+ pinout, MAX17610ATC+ application, or MAX17610ATC+ equivalent, this page delivers verified functional boundaries, thermal shutdown behavior, reverse-blocking response time (150ns fast mode), current-limit mode selection (Autoretry/Continuous/Latch-off), and confirmed TDFN-EP (3mm × 3mm, 12-pin) package compatibility - all validated against Maxim's official MAX17610 datasheet Rev 1 (6/2018).

Technical Context

The MAX17610ATC+ implements two series-connected N-channel MOSFETs with integrated gate control, enabling bidirectional fault detection but unidirectional power flow (IN→OUT only). Its reverse-current protection uses dual thresholds - slow (11mV, 140μs debounce) and fast (105mV, 150ns response) - to distinguish noise from hard shorts at the output.

Overvoltage and undervoltage lockout are fixed internally (no external pins), unlike MAX17608/MAX17609; instead, it relies on its default 4V UVLO and inherent OV tolerance up to +60V. Current regulation is achieved by modulating FET resistance in real time, with SETI providing a voltage proportional to load current (V_SETI = I_IN × R_SETI) for ADC-based monitoring.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	+4.5V to +60V DC - supports wide industrial supply rails including 24V and 48V systems without external clamping.
Reverse Input Tolerance	–65V - blocks negative transients during hot-swap or load-dump events without external TVS diodes.
Current-Limit Range	0.1A to 1.0A - set via single resistor (R_SETI); ±3% accuracy from 0.2A–1.0A ensures reliable inrush control for capacitive loads.
On-Resistance (R_ON)	260mΩ (typ) - minimizes power loss (≤260mW at 1A) and self-heating in compact 3mm × 3mm layout.
Reverse-Blocking Threshold	11mV (slow), 105mV (fast) - enables noise-immune detection of backfeed while reacting in <150ns to catastrophic reverse faults.
Operating Temperature	–40°C to +125°C - qualified for extended-range industrial environments including factory-floor sensors and weighing systems.
Thermal Shutdown	160°C (with 28°C hysteresis) - prevents permanent damage during sustained overload or poor PCB thermal design.

Pinout & Package

MAX17610ATC+ is housed in a thermally enhanced 12-pin TDFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed pad (EP) requiring connection to a large GND plane via multiple thermal vias for optimal power dissipation (θ_JA = 41°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1–2, IN	High-voltage input node	Accepts +4.5V to +60V; must be decoupled with ≥0.47µF ceramic capacitor close to pins 1–2.
3–4, N.C.	No-connect terminals	Internally unused; must remain unconnected per datasheet.
5, EN	Active-high enable control	Drives internal FETs ON when >1.4V; internal 1.8V pullup allows single-resistor enable logic.
6, CLMODE	Current-limit response mode selector	Unconnected = Autoretry; GND = Continuous; 150kΩ-to-GND = Latch-off - configures fault recovery behavior.
7, GND	Power and signal reference	Primary return path; EP pad must connect to same GND plane for thermal and electrical integrity.
8, SETI	Current-limit programming & monitoring	R_SETI-to-GND sets I_LIM; V_SETI = I_IN × R_SETI provides analog current readout for system ADC.
9, FWD	Forward-fault open-drain indicator	Pulled low during overcurrent (t_BLANK exceeded), thermal shutdown, or R_SETI <1kΩ - requires external pullup.
10, REV	Reverse-fault open-drain indicator	Pulled low upon detection of reverse current (V_OUT–V_IN >105mV fast or >11mV slow) - enables discrete fault isolation.
11–12, OUT	Protected output node	Delivers regulated current to load; layout must minimize trace inductance for fast transient response.
EP	Exposed thermal pad	Not electrically active; soldered to GND plane to dissipate up to 1.95W at T_A=70°C.

Key Features

Feature	Design Value
Dual-threshold reverse-current blocking	11mV (slow, 140μs debounce) and 105mV (fast, 150ns response) - rejects EMI while protecting against hot-plug shorts at OUT.
Programmable current-limit accuracy	±3% from 0.2A–1.0A over full temperature range - enables repeatable inrush control for battery-backed or high-C_OUT systems.
Three configurable fault responses	Autoretry (600ms off-time), Continuous (constant I_LIM), or Latch-off (requires EN toggle/reset) - matches system-level fault-handling strategy.
Integrated current-sense ratio	CIRATIO = 1000 A/A (±3%) - delivers precise V_SETI = I_IN × R_SETI for real-time load current telemetry without external amplifiers.
Fixed internal UVLO at 4V (typ)	No external resistors needed - simplifies BOM and layout vs. MAX17608/09; ensures startup only above brownout-safe level.

Equivalent & Alternatives

The following parts are listed as comparable options for similar overvoltage/overcurrent protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX17608ATC+	Includes OVLO/UVLO adjustment pins (OVLO, UVLO); no REV/FWD pins - uses FLAG/UVOV instead; supports reverse-current blocking but lacks dedicated REV output.	Preferred when system requires user-configurable UV/OV thresholds and shared fault signaling (single FLAG line).	Select MAX17608ATC+ if adjustable lockout thresholds are required and board space permits additional resistor dividers.
TPS26631RGZR	Fixed 5.5V–60V OVLO; no reverse-current blocking; 1.2A current limit; integrated charge pump; smaller 10-pin WQFN (3mm × 3mm).	Better suited for cost-sensitive, non-reverse-blocking applications where thermal performance is less critical (θ_JA = 50°C/W).	Choose TPS26631RGZR only if reverse-current protection is unnecessary and lower quiescent current (25μA shutdown) is prioritized.

Compared with MAX17608ATC+, MAX17610ATC+ trades adjustable OV/UV thresholds for dedicated reverse-fault signaling (REV pin) and simplified layout; versus TPS26631RGZR, it adds critical reverse-blocking capability and tighter current-limit accuracy at the cost of slightly higher supply current (1.2mA typical).

FAQ

What protection functions does the MAX17610ATC+ provide?

The MAX17610ATC+ provides overvoltage protection up to +60V, undervoltage lockout at 4V (typ), reverse-current blocking with dual thresholds (11mV slow / 105mV fast), programmable current limiting (0.1A–1.0A), and thermal shutdown at 160°C. It does not support externally adjustable OVLO/UVLO - those pins are omitted in MAX17610ATC+, distinguishing it from MAX17608/MAX17609 variants.

How is current limiting configured on the MAX17610ATC+?

Current limiting on the MAX17610ATC+ is set by connecting a resistor (R_SETI) from the SETI pin to GND. Using R_SETI = 1.5kΩ yields 1.0A limit; 3kΩ gives 0.5A. Accuracy is ±3% for limits ≥0.2A. The SETI pin also outputs V_SETI = I_IN × R_SETI, enabling real-time current monitoring by an external ADC without additional sensing components.

Does the MAX17610ATC+ support reverse current flow from OUT to IN?

No - the MAX17610ATC+ actively blocks reverse current flow (OUT to IN) using dual-threshold detection: slow-mode triggers at 11mV (140μs debounce) and fast-mode at 105mV (150ns response). When triggered, the REV pin asserts low. This distinguishes MAX17610ATC+ from MAX17609, which allows reverse conduction, and aligns it with MAX17608's blocking behavior.

What package type and thermal considerations apply to the MAX17610ATC+?

The MAX17610ATC+ uses a 12-pin TDFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed thermal pad (EP). For reliable operation at full 1A load, EP must be soldered to a solid GND plane with ≥4 thermal vias. Junction-to-ambient thermal resistance is 41°C/W on a four-layer board; derating begins above +70°C ambient (24.4mW/°C).

Can the MAX17610ATC+ be used in hot-swap applications without external TVS diodes?

Yes - the MAX17610ATC+ tolerates +60V input surges and –65V negative transients without external TVS diodes, and its 260mΩ R_ON and fast reverse-current response (150ns) make it suitable for hot-swap scenarios. However, for >35V input surges, Maxim recommends adding a 0.47µF input capacitor (as shown in Typical Operating Circuits) to absorb high-frequency energy before the IC.
