MAX17525ATP+

The MAX17525ATP+ is a high accuracy, adjustable power limiter in 20 pin TQFN package. This adjustable overvoltage, undervoltage and overcurrent protection device guards systems against overcurrent faults in addition to positive overvoltage and reverse voltage faults. When used with an optional external pMOSFET, the device also protects downstream circuitry from voltage faults up to ±60V (for -60V external pFET rating). The device features a low 31mohm on-resistance integrated FET. During start-up, the device is designed to charge large capacitances on output in a continuous mode for applications where large reservoir capacitors are used on the inputs to downstream devices. Additionally, the device features a dual stage, current limit mode in which the current is continuously limited to 1x programmed limit. This enables faster charging of large loads during start-up. It is typically used in motion system drives, human machine interfaces, high power applications, control and automation.

• Programmable forward current limit from 0.6A to 6A with ±15% accuracy over full temperature range
• Shutdown IN current of 4μA (VIN <lt/> 40V) and supply current of 1.4mA
• Robust, high power protection reduces system downtime
• Wide operating input range from 5.5V to 60V
• -60V negative input tolerance with external pFET (for -(60 + VOUT) external pFET rating)
• Saves board space and reduces external BOM count
• Reverse current blocking protection with external pFET
• Enables fast start-up and brownout recovery
• Flexible design enables reuse
• Operating temperature range from -40°C to +125°C
