Datasheet Voltage Detector (Reset) IC Series for Automotive Application Free Time Delay Setting CMOS Voltage Detector (Reset) IC BD52xx-2C Series and BD53xx-2C Series General Description ROHM's BD52xx-2C and BD53xx-2C series are highly accurate, low current consumption Voltage Detector ICs with a capacitor controlled time delay. The lineup includes N-channel open drain output (BD52xx-2C) and CMOS output (BD53xx-2C) so that the users can select depending on the application. The devices are available for specific detection voltage ranging from 0.9V to 5.0V with 0.1V increment. The time delay has ±50% accuracy in the overall operating temperature range of -40°C to 125°C. Special Features  AEC-Q100 Qualified (Note1)  Nano Energy  Delay Time Setting controlled by external capacitor  Two output types (Nch open drain and CMOS output)  Very small, lightweight and thin package  Package SSOP5 is similar to SOT-23-5 (JEDEC) (Note1: Grade 1) Key Specifications  Detection Voltage: 0.9V to 5.0V (Typ.) 0.1V step  Ultra-Low Current Consumption: 270nA (Typ.)  Time Delay Accuracy: ±50% (-40°C to +125°C, ) (CT pin capacitor ≥ 1nF) Special Characteristics  Detection Voltage Accuracy: ±3%±12mV (VDET=0.9V to 1.6V) ±3% (VDET=1.7V to 5.0V) Package SSOP5: W(typ) x D(typ) x H(max) 2.90mm x 2.80mm x 1.25mm Application All automotive devices that requires voltage detection Application Circuit VDD1 CCT BD52xx-2C RL Microcontroller RST VDD2 VDD1 CCT BD53xx-2C Microcontroller RST Figure 1.

The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
