BU52004GUL-E2

Hall IC Series Omnipolar Detection Hall ICs (Polarity detection for both S and N features dual outputs) No.10045EDT01 BU52004GUL, BU52014HFV 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 Supply Supply current Operate point Hysteresis Period Product name voltage (AVG. ) Output type Package (mT) (mT) (ms) (V) (A) BU52004GUL 2.40 3.30 +/-3.7 0.8 50 8.0 CMOS VCSP50L1 BU52014HFV 1.653.30 +/-3.0 0.9 50 5.0 CMOS HVSOF5 Plus is expressed on the S-pole minus on the N-pole Absolute Maximum Ratings BU52004GUL (Ta=25) PARAMETERS SYMBOL LIMIT UNIT 1 Power Supply Voltage VDD -0.1 ~ +4.5 V Output Current IOUT 1 mA 2 Power Dissipation Pd 420 mW Operating Temperature Range Topr -40 ~ +85 Storage Temperature Range Tstg -40 ~ +125 1.
