BU52014HFV

Hall IC Series Omnipolar Detection Hall ICs (Polarity detection for both S and N features dual outputs) BU52004GUL, BU52014HFV No.10045EDT01 ●Description The BU52004GUL and BU52014HFV are bipolar Hall ICs incorporating a polarity determination circuit that enables operation (output) on both the S- and N-poles, with the polarity judgment based on the output processing configuration. These Hall IC products can be in with movie, mobile phone and other applications involving crystal panels to detect the (front-back) location or determine the rotational direction of the panel. ●Features 1) Omnipolar detection (polarity detection for both S and N features dual outputs) 2) Micropower operation (small current using intermittent operation method) 3) Ultra-compact CSP4 package(BU52004GUL) 4) Small outline package (BU52014HFV) 5) Line up of supply voltage For 1.8V Power supply voltage (BU52014HFV) For 3.0V Power supply voltage (BU52004GUL) 6) Polarity judgment and output on both poles (OUT1: S-pole output; OUT2: N-pole output) 7) High ESD resistance 8kV(HBM) ●Applications Mobile phones, notebook computers, digital video camera, digital still camera, etc. ●Product Lineup Product name BU52004GUL BU52014HFV Supply voltage (V) 2.40～3.30 1.65～3.30 Operate point (mT) +/-3.7 +/-3.0 ※ ※ Hysteresis (mT) 0.8 0.9 Period (ms) 50 50 Supply current (AVG. ) (μA) 8.0 5.0 Output type CMOS CMOS Package VCSP50L1 HVSOF5 ※Plus is expressed on the S-pole; minus on the N-pole ●Absolute Maximum Ratings BU52004GUL (Ta=25℃) PARAMETERS Power Supply Voltage Output Current Power Dissipation Operating Temperature Range Storage Temperature Range ※1.
