MAX17613A/ 4.5V to 60V, 3A Current-Limiter with MAX17613B/ OV, UV and Reverse Protection MAX17613C General Description Benefits and Features The Olympus series of ICs is the industry s smallest and Robust Protection Reduces System Downtime most robust integrated system protection solution. The Wide Input-Supply Range of +4.5V to +60V MAX17613A/MAX17613B/MAX17613C adjustable over- Hot Plug-in Tolerant without TVS up to 35V Input voltage and overcurrent protection devices are ideal to Supply protect systems against positive and negative input volt- Negative Input Tolerance up to -65V age faults up to +60V and -65V, and feature low 130m Low R 130m (typ) ON (typ) R FETs. ON Reverse Current-Blocking Protection The adjustable input overvoltage protection range is 5.5V Thermal Overload Protection Programmable Startup Blanking Time to 60V and the adjustable input undervoltage protec- Extended -40C to +125C Temperature Range tion range is 4.5V to 59V. The input overvoltage-lockout MAX17613A Enables OV, UV, and Reverse Voltage (OVLO) and undervoltage-lockout (UVLO) thresholds are Protection set using external resistors. Additionally, the devices offer MAX17613B Enables OV and UV Protection an internal input undervoltage threshold at 4.2V (typ). MAX17613C Enables Reverse Voltage Protection The devices feature programmable current-limit protection Flexible Design Options Enable Reuse and Less up to 3A hence, controlling the inrush current at startup Requalification while charging high capacitance at the output. The current- Adjustable OVLO and UVLO Thresholds limit threshold is programmed by connecting a resistor from Programmable Forward Current Limit: the SETI pin to GND. When the device current reaches 0.15A to 3A with 3.5% Accuracy the programmed threshold, the device prevents further Accuracy Over Full Temperature Range increases in current by modulating the FET resistance. The Programmable Overcurrent Fault Response: devices can be programmed to behave in three different Autoretry, Continuous, and Latchoff Modes ways under current-limit condition: autoretry, continuous, Smooth Current Transitions or latchoff modes. The voltage appearing on the SETI pin Saves Board Space and Reduces External BOM is proportional to the instantaneous current flowing through Count the device and can be read by an ADC. 20-Pin, 4mm x 4mm, TQFN-EP Package Integrated MAX17613A and MAX17613C block current flowing FETs in the reverse direction (i.e., from OUT to IN) whereas MAX17613B allows current flow in the reverse direction. Applications The devices feature thermal shutdown protection against Sensor Systems excessive power dissipation. Condition Monitoring The devices are available in a small, 20-pin (4mm x 4mm) Factory Sensors TQFN-EP package and operate over the -40C to +125C extended temperature range.
