NJU7329B

NJU7329B Single-phase DC Brushless Motor Driver IC ■ GENERAL DESCRIPTION The NJU7329B is a single-phase DC brushless motor driver IC designed for small and high power fan-motor applications. It provides a low operating current of 3mA (typ.) and low saturation output voltage at high output current operation, which offers a high efficiency motor driving. Further it has a frequency generator (FG) output useful for various control systems and protection circuits such as a lock protection, auto-recovery circuit and thermal shutdown useful for high-current applications. The NJU7329B is available in a small and thin surface mount package of MSOP10 (TVSP10), which proves downsizing and thinning in motor applications. ■ PACKAGE OUTLINE NJU7329BRB2 (MSOP10(TVSP10)) ■ FEATURES  Operating Voltage VDD=2.4 to 5.5V  Low Operating Current IDD=3mA typ.  Low Saturation Output Voltage VOM=0.35V at IO=350mA  Internal Thermal Shutdown Circuit (with hysteresis)  Internal Lock Detect / Auto Recovery Circuit (with idling prevention function )  FG Output (open drain)  C-MOS Technology  Package Outline MSOP10 (TVSP10)* *MEET JEDEC MO-187-DA / THIN TYPE ■ BLOCK DIAGRAM ■ PIN CONFIGURATION 1: N.C. 2: OUT A 3: IN4: IN+ 5: GND 6: N.C. 7: Ct 8: FG 9: OUT B 10: VDD Ver.2014-04-14 -1- NJU7329B ■ ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Input Voltage Output Current (Peak) Operating Temperature Range Storage Temperature Range Power Dissipation RATINGS +7.0 -0.3 ~ VD...
