The devices are extremely fast responding with lower levels of emissions (EMI) than a design using chopper stabilization. This Hall-effect latch IC features extended AEC-Q100 qualification and is ideal for high-temperature operation up to 175°C junction temperatures. In addition, the APS12170 includes a number of features designed specifically to maximize system robustness, such as reverse-battery protection, overvoltage, and EMC protection. A south pole and a north pole of sufficient strength are both necessary to actuate the device. The devices include on-board transient protection for all pins, permitting operation directly from a vehicle battery or regulator with supply voltages from 3.8 to 16 V. Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified 3-pin SOT23W surface-mount package, while UA is a three-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free and Ro HS pliant, with 100% matte-tin-plated leadframes. APPLICATIONS - Seat/window motors - Sun roof/convertible top/liftgate/tailgate actuation - Automotive and...
