LB1862

Ordering number : EN6208B LB1862 Monolithic Digital IC For Fan Motor Single-Phase Full-Wave Driver http://onsemi.com Overview Single-phase full-wave drive design and a compact package make these ICs optimal for small fans (especially CPU cooling fans). Low switching noise and effective motor drive are further advantages. Functions Support for 5V/12V dual power supply voltage Built-in regenerative circuit allows use of reverse connection protection diode Built-in Hall amplifier with hysteresis (supports core without auxiliary electrode) Built-in lockup protection and automatic recovery circuits Latch-type lockup detection output (RD) is Low during rotation and High during stop Hall bias pin and start/stop pin allow reduced current drain in standby mode Built-in thermal protection circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output current Maximum output withstand voltage RD maximum output withstand voltage RD maximum output current HB maximum output current ST maximum input voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max IOUT max VOUT max VR max IR max IB max VST max Pd max Topr Tstg Conditions Ratings 17 0.8 17 17 5 10 15 1.0 -30 to +85 -55 to +150 Unit V A V V mA mA V W °C °C Stresses exceeding Maximum Ratings may damage the device.
