MAX17613BATP+ 개요
A protection IC such as the MAX17613B belongs to the broader category of specialized power-management semiconductors. System-protection ICs sit between an upstream DC rail (USB, industrial 24V, battery, or PoE) and a downstream load, and their job is to disconnect the load within microseconds when the input voltage, current, or polarity strays outside a safe window. Within that family, the MAX17613B is the OV/UV-and-OC variant (the 'B' suffix) of the Olympus trio, sharing the same TQFN-20 footprint with the MAX17613A (OV/OC only) and MAX17613C (OV/UV/OC plus reverse-current blocking).
Key features include a 4.5V-to-60V operating input range, a -65V negative-fault tolerance, internal 130 mOhm RON FET, adjustable OV/UV/OC thresholds via external resistors, and a fault FLAG output. The IC also supports parallel-mode current sharing for loads above 3A and provides thermal-shutdown protection. Quiescent current is typically 480 uA in normal operation, dropping to a few microamps in shutdown.
The internal architecture combines a charge pump driving an N-channel MOSFET, a precision bandgap reference for the OV/UV comparators, and a current-sense amplifier that monitors the FET drain-to-source voltage for the OC loop. The device also integrates reverse-current blocking, which prevents current backflow into the source when the input collapses - a critical feature for USB-C and battery-powered systems.
Typical applications include industrial PLC I/O protection, USB-C source power delivery, eMobility/EV auxiliary rails, 24V factory automation, battery-pack protection, and any 12V/24V/48V system that must survive load-dump transients. The compact 4x4 mm package and high integration reduce BOM cost compared with discrete TVS+fuse+MOSFET solutions.
When designing with this device, derate output current based on PCB thermal performance; the TQFN-20 exposed pad must be soldered to a sufficient copper pour. Use Kelvin-sense layout at the OUT pin to keep OC threshold accuracy within +/-10 percent across temperature.

일반적인 애플리케이션
MAX17613BATP+ 적합 용도: 7 애플리케이션s: Industrial 24V PLC I/O Protection, USB-C PD Source Power Delivery, eMobility and EV Auxiliary Rails, 24V Factory Automation Sensors, Battery-Pack Protection and Hot-Swap, 12V/24V Test and Measurement Front-End, Solar and Renewable Energy Junction Boxes.
Industrial 24V PLC I/O Protection
The MAX17613BATP+'s 4.5V-to-60V operating window and -65V negative-fault tolerance make it ideal for industrial 24V PLC and sensor I/O rails that must survive miswiring, load-dump, and reverse-polarity events. Placed between the field-side connector and the isolated DC-DC, it interrupts the path within microseconds when OV exceeds the set threshold (typically 36V) or UV drops below 18V. The 130 mOhm RON keeps steady-state dissipation around 250 mW at the typical 1.4A load, so no heatsink is needed.
추천
USB-C PD Source Power Delivery
USB-C power-delivery source designs need OV/UV/OC protection on the VBUS rail before the PD controller. The MAX17613BATP+ provides 5V-to-20V VBUS protection at 3A continuous (60W PD) with the internal 130 mOhm FET, while its -65V rating absorbs the negative transients generated by sudden cable disconnects. Used between the DC input and the PD controller, it cuts off the load on overcurrent within 5 us, protecting downstream PD controllers and battery chargers from hot-plug faults.
추천
eMobility and EV Auxiliary Rails
Electric two-wheelers, e-bikes, and 12V/48V EV auxiliary systems rely on the MAX17613BATP+ to protect low-voltage electronics from 60V load-dump transients generated by the traction inverter. The -65V reverse-fault tolerance handles the back-EMF pulses that occur when the motor regenerates into a discharged battery. Its small 4x4 mm TQFN footprint fits inside handlebar-mounted controller modules, and the 3A rating covers headlight, instrument-cluster, and accessory rails in a single IC.
추천
24V Factory Automation Sensors
Industrial sensor backplanes, valve manifolds, and motor-driver boards use the MAX17613BATP+ on each 24V branch to limit fault propagation to a single module. With OV typically set to 32V and UV to 18V, the IC disconnects a shorted sensor before the upstream 24V bus collapses, preventing cascading shutdowns. Parallel-mode capability allows two MAX17613Bs to share current above 3A for higher-power actuator channels.
추천
Battery-Pack Protection and Hot-Swap
Multi-cell Li-ion battery packs and 48V telecom battery shelves use the MAX17613BATP+ as a hot-swap controller on the positive rail. Its adjustable undervoltage threshold prevents deep discharge below the cell cutoff, and the 4.5V minimum operating voltage is compatible with 1S Li-ion packs. The integrated reverse-current blocking is essential when parallel battery strings share a common bus, preventing current backflow from a healthy string into a depleted one.
추천
12V/24V Test and Measurement Front-End
Bench-top instruments, data-acquisition modules, and field-test equipment use the MAX17613BATP+ as the front-end protection on external trigger and power inputs. Engineers rely on its 60V OV threshold to clamp inductive kickback from relay coils and long cable harnesses, and on the FLAG output to trigger a microcontroller interrupt that latches the fault for diagnostic display. Its 130 mOhm RON keeps measurement-path ground-shift below 2 mV at 1A, preserving ADC accuracy.
추천
Solar and Renewable Energy Junction Boxes
Solar combiner boxes and small wind-turbine charge controllers use the MAX17613BATP+ to protect downstream MPPT converters from overvoltage events caused by sudden load disconnect. Its 60V continuous and -65V reverse tolerance handle the back-EMF generated when a turbine blade is feathered, while its 3A continuous load rating covers sub-100W residential solar strings. The exposed-pad TQFN simplifies thermal dissipation in outdoor enclosures without active cooling.

설계 노트
Estimated: at 3A through the 130 mOhm internal FET, steady-state dissipation is about 1.17 W. The 20-TQFN package's thermal performance depends almost entirely on the exposed-pad copper pour - a minimum 1 square inch of 1-oz copper keeps theta_JA around 35 C/W and the temperature rise under 45 C above ambient. Without the pad soldered or with copper arriving, junction temperature can exceed the 150 C absolute-max limit at full load, so always flood at least the top layer under the IC with thermal copper connected by 5 to 8 vias to the inner ground plane.
Use a Kelvin-sense layout at the OUT pin: separate the high-current OUT trace from the sense trace used by the SETI current-limit comparator, and tie both back to the device pin with a single via each. Place the SETI resistor (typically 10 kOhm to 100 kOhm) within 5 mm of the SETI pin to avoid noise pickup. Keep the FLAG pull-up resistor near the IC and route the FLAG trace away from the OUT power path to prevent false triggering during high di/dt events. Decouple IN with a 1 uF X7R ceramic plus a 10 uF bulk tantalum or aluminum-polymer capacitor placed within 3 mm of the IN pins.
Three pitfalls are common on first prototypes: (1) leaving the exposed pad unsoldered, which causes thermal runaway at loads above 2A; (2) using a UV threshold setpoint inside the regulator's normal operating range, which forces the IC into constant re-start cycling instead of clean shutdown; (3) driving the EN pin with a slow RC ramp longer than 1 ms, which can cause in-rush faults and spurious FLAG assertions. According to the Analog Devices datasheet, OV and UV are programmed with resistor dividers from IN to GND - typical values are R-top = 100 kOhm, R-bottom tuned for the desired threshold. Always add a 100 kOhm resistor in series with the UV pin if you tie UV directly to IN to limit fault current during severe UV events.
For parallel-mode current sharing above 3A, place two MAX17613B ICs within 25 mm of each other and tie their OUT, IN, FLAG, and SETI pins together directly with low-impedance traces. The ICs automatically balance the load current within +/-15% if the SETI resistor is shared; do not use separate SETI resistors. The combined thermal pad copper area must be doubled (at least 2 square inches) to keep junction temperatures below 110 C at 5A combined load.
