HL85875

The HL85875 is an eight-channel power switch, with two fixed HS drivers and six configurable HS/LS drivers. The device offers diagnosis, full protections and high precision current monitor function, it can realize intelligent control of the load and improve the safety level of the system. The eight channels can be either driven by SPI or by two dedicated parallel inputs. HL85875 also features Limp home mode, which allows using two selected drivers in fault conditions, such SPI fault, micro fault or supply UV. An internal power FET drain to source voltage clamp is implemented to address the switching off energy of the inductive loads, such as relays, valve, motors, etc.. During the inductive load switching off cycle, both the energy of the power supply (EBAT) and the load (ELOAD) are dissipated on the high side power switch itself. The HL85875 can achieve excellent power dissipation capacity, which can help save the external free-wheeling circuitry in most cases. In automotive application scenarios, the short-circuit reliability of the high side power switch device is critical. To address this, the AEC Q100-012 defines the test standard for the device continuous short. Different levels are divided according to the number of the pass cycles. The device is certified to the highest level, Class A, 1 million shorts to ground. The HL85875 device can be used as a high side power switch for a wide variety of resistive, inductive, and capacitive loads, including the low-wattage bulbs, relays, and valves, etc. This device operates over a -40°C to +150°C junction temperature range. The HL85875 is available in a 24-pin HTSSOP package.
