Description
MAX17614 Click here to ask an associate for production status of specific part numbers. 4.5V to 60V, 3A, Ideal Diode/Power Source Selector with Current Limit, UV, OV Protection Product Highlights • Ideal Diode Operation • Fast Reverse Current-Blocking Protection(140ns) • Seamless Power Source Switchover • Robust Protection Reduces System Downtime
More View • Wide Input Supply Range: +4.5V to +60V • Hot Plug-in Tolerant without transient voltage suppressor (TVS) up to 35V Input Supply • Negative Input Tolerance to -65V • Low RON 130mΩ (typ) • Thermal Shutdown Protection • Programmable Startup Blanking Time • Extended -40°C to +125°C Temperature Range • Flexible Design Options Enable Reuse and Less Requalification • Adjustable Input Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) Thresholds • Programmable Forward-Current Limit: 0.15A to 0.3A with +3.6% and -3.3% Accuracy and 0.3A to 3A with ±3.3% Accuracy Over Full Temperature Range • Programmable Current Limit Fault Response: Autoretry, Continuous, and Latch-Off Modes • Built-in Fault Indication Signals: UVOV and FLAG • Saves Board Space and Reduces External BOM Count • 20-Pin, 4mm x 4mm, TQFN-EP Package • Integrated Back-to-Back nFETs Key Applications • Small Total Solution Size The MAX17614 with its integrated nFETs enables up to 40% smaller solution size in space-constrained equipment. Applications include ideal diode implementations and power source selectors where the end equipment needs to supply the load from more than one power source. • Faster Response Times Faster fault exit response times enable the MAX17614 to reduce output hold-up capacitor size up to 50% in Priority Power Source Selector applications, where the end equipment input supply transitions between a higher priority power source and a backup power source. • Tight Current Limit Accuracy Battery-operated electronics as well as battery chargers need tight current limit accuracy to protect against overcurrent faults. The MAX17614 with its ±3.3% tight current limit accuracy provides robust overcurrent protection in these applications.
