BD950F51EFJ-C (In Entwicklung)
Nano Cap™, 500mA 5.0V, Fixed Output LDO Regulators for Automotive with WDT and Voltage Supervisor (Reset)
The BD9xxF5-C series are linear regulators using the Nano Cap™ topology(Note 1) designed as low currentconsumption components for power supplies in various automotive applications requiring a direct connection to the battery. It integrates a reset block(RESET) that monitors the input voltage of the microcomputer and a watchdog timer block(WDT) that monitors the clock signal of the microcomputer. The RESET delay time and WDT monitor time can be adjusted through an external capacitor. These products are designed for an absolute maximum input voltage of 45V and to operate at up to 500mA of current load with a low current consumption of 32μA(Typ). Output voltage regulation is guaranteed to be highly accurate at ±2%. An output capacitor of 470nF(Typ) or more can be used for this product series and it has excellent transient characteristics even with small output capacitance. It has an output shutdown function. A logical HIGH at the EN pin turns on the product output and a logical LOW disable the output. The products feature an integrated Over Current Protection to protect the device from damage caused by a short circuit or an overload. These products also integrate Thermal Shutdown Protection to avoid damage by overheating and Under Voltage Lock Out to avoid false operation at low input voltage. Furthermore, low ESR ceramic capacitors are sufficient for phase compensation. Additionally, this IC functions as a ComfySIL™(Note 2) compatible product, to support functional analysis related to functional safety. (Note 1): Nano Cap™ is a combination of technologies which allow stable operation even if output capacitance is connected with the range of nF units.
(Note 2): ComfySIL™ is awarded to products that conform to the ComfySIL™ concept for functional safety in the industrial equipment and automotive markets.
(Note 3): QuiCur™ is a combination of technologies that provides high-speed load response.
