| WSH610 Hall Effect IC with Two-Step Lock Protection and Auto-Restart Function Features: Operate from 2.8V to 20V supply voltage. On-chip Hall sensor. Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. High output sinking capability up to 600mA for driving large load. Available in rugged low profile SOT-25 , SIP-4L packages. Built-in protection diode for reverse power supply fault. Built-in 2-Step Lock protection and auto-restart function. General Description: WSH610 is designed to integrate Hall sensor with complementary output drivers and 2-Step thermal protection circuit together on the same chip. It is carefully designed to protect DC brushless motors to operate on different fault operating condition. WSH610 can detect whether motor is in locked or operating condition then trigger the low or high temperature protection to protect motor under safety operating zone. This technique allows motors to operate as high temperature as 125C and keep motor under 80C low temperature when motor is locked. And all above protection will be disabled when fault condition is removed and motor will be auto-restarted. WSH610 includes two open collector output drivers, each capable of sinking 600mA current load. An on-chip protection diode is implemented to prevent reverse power fault. Its 2-step protection can replace traditional lock protection and auto restart function but without EMI noise and any external components with much lower cost. The temperature-dependent bias increases the supply voltage of the hall plates and adjusts the switching points to the balance the influence of magnets at higher temperatures. WSH610 are rated for operation on wide temperature range from -20 C to 125C and voltage ranges from 2.8V to 20V. Winson reserves the right to make changes to improve reliability or manufacturability.
