AH5771 SINGLE PHASE HALL EFFECT LATCH SMART FAN MOTOR CONTROLLER General Description Features • • • • • Support single-phase full wave min fan driver Built-in Hall sensor input amplifier Low voltage startup ( Vdd=2.5V ) Lock detection and automatic self-restart Without external timing capacitor, Reduces the numbers of external component required Low profile package : SIP-4L SIP-4L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish / RoHS Compliant (Note 1) • • • AH5771 is the integrated Hall sensor with output drivers designed for electrical commutation of brush-less DC motor application. The device is as follows: one-chip Hall voltage generator for magnetic sensing; the error amplifier that amplifies the Hall voltage; a comparator is to provide switching hysteresis for noise rejection; the full bridge driver for sinking and driving current load. Internal band gap regulator is used to provide temperature compensated bias for internal circuits and allows a wide operating supply voltage range. The device includes features such as Rotor Lock Protection with rotor lock detection and automatic self-restart to avoid damage to the coil when the rotor is blocked. AH5771 is rated for operation over-temperature range from -40℃ to 100℃ and voltage range from 2.5V to 15V. The device is available in low profile package SIP-4L. Typical Application Circuit POWER D1 V dd AH5771 D2 O1 O2 C V SS Note: D2 (Zenor Diode) and Capacitor C are for power stabilization, D2 is recommended to be 18Vz (option), C is recommended to 0.1uF ~1uF (E-Cap). D1 (reverse Diode) is for reverse voltage protection.
