Nisshinbo Micro Devices Inc. R5115S011A-E2-KE

The R5115x is a system power supply IC with an ultra-low power window-type watchdog timer (VR + VD + WDT) that has an input voltage range of 3.5 V to 42 V.

• Consists of a voltage regulator, a voltage detector and a watchdog timer that provides a system power supply, a power supply voltage monitoring and a system malfunction monitoring.
• Equipped with an auto monitoring stop (1) to cease the watchdog timer monitoring at light load.
• Outputs a reset signal from watchdog timer when a pulse signal period is too short or too long.
• Input Voltage Range (Absolute Maximum Rating): 3.5 V to 42.0 V (50.0 V)
• Supply Current: Typ. 8.5 μA
• Protections: Thermal Shutdown, Output Current Limiting, Short-circuit Current Limiting
• Output Voltage Range: 3.3 V to 5.0 V
• Output Voltage Accuracy: ±1.6% (-40°C ≤ Ta ≤ 125°C)
• Output Current: 250 mA
• Detection Voltage Threshold Range: 2.5 V to 4.8 V
• Detection Voltage Accuracy: ±1.6% (-40°C ≤ Ta ≤ 125°C)
• Watchdog Timer Accuracy (tow): -17.8% to 21.7% (-40°C ≤ Ta ≤ 125°C)

• Microprocessor-based Electronic Equipment for Automotive Applications
