In its lowest cost configuration the IC can operate without an external microcontroller. The device requires no programming, as key parameters and functions &#8211; such as startup and speed setting &#8211; can be configured via SPI interface and stored in embedded non-volatile (OTP) memory. Open-loop and closed-loop speed control are possible. For more complex applications the LV8907UW can also support a small microcontroller with its integrated linear regulator (3.3V or 5V, 50 mA), a local interconnect network (LIN) transceiver for automotive connectivity, and a watchdog timer.<\/p>\n<p class=\"western\" style=\"margin-bottom: 0cm\">&nbsp;<\/p>\n<p class=\"western\" style=\"margin-bottom: 0cm\">AEC-Q100 qualified, the LV8907UW\u2019s operational temperature range extends to 175\u00b0C, for automotive environments. Integrated protection mechanisms include over-current, over-voltage, short circuit, under-voltage, and over-temperature. ON suggests use in automotive water pumps, oil pumps, fuel pumps, HVAC systems, radiator fans, and headlamp cooling units.<\/p>\n<p class=\"western\" style=\"margin-bottom: 0cm\">&nbsp;<\/p>\n<p
