High Noise Immunity 42 V/70 mATo be Compliant with AEC-Q100Voltage Tracker Designed with techniques for electromagnetic noise immunity to prevent malfunction with fewer externalcomponents for EMICLIENT’S CONCERNS Concerns about noise from communication devices, etc. affecting operation of systems using sensors Countermeasure components for EMI lead to increase of cost and mounting area. RICOH’S SOLUTIONS High noise immunity enables the construction of systems with robust resistance to EMI. Fewer countermeasure components for EMI such as external filters, means a smaller equipment footprint. Excellent immunity reduces rework after input noise tests. When voltage is supplied to off-board sensors like those below, wiring such as harnesses is affected by Stable output with high-frequency noise electromagnetic noise, which flows into the IC’s VOUT ⇒ IC contributes to system safety. pin. ⇒ EMI-resistant components are required forDPI testthe IC.electromagnetic noise +B ECUelectromagnetic noise flowsinto the VOUT pin as VDD conductive noise.
