A1230
FEATURES AND BENEFITS - AEC-Q100 automotive qualified - Two matched Hall-effect switches on a single substrate - 1 mm Hall element spacing - Superior temperature stability and industry-leading jitter performance through use of advanced chopperstabilization topology - Integrated regulator provides 3.3 V operation - Integrated ESD protection from outputs and VCC to ground - High-sensitivity switch points - Robust structure for EMC protection - Solid-state reliability - Reverse-battery protection on supply and both output pins PACKAGES: 8-Pin SOIC (suffix L) 4-Pin SIP (suffix K) Not to scale DESCRIPTION The A1230 is a dual-channel, bipolar switch with two Halleffect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photolithographically aligned to better than 1 µm. Maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in...
