TA7712FG

TA7712P/PG/F/FG TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7712P/PG,TA7712F/FG 3-Phase, Full-Wave Brushless DC Motor Controller IC FEATURES z No frequency generator (FG) required (The rotation signal is derived from the position sensor signal.) z Start, Stop, clockwise (CW), counterclockwise (CCW) and Brake z High-gain position sensor with input hysteresis z Rotation signal output (with a frequency six times that of the position sensor output (Hall effect output)) z External transistors are required. The TA7712PG/FG: The TA7712PG/FG is a Pb-free product. About solderability, following conditions were confirmed Solderability (1) Use of Sn-37Pb solder Bath · solder bath temperature = 230°C · dipping time = 5 seconds · the number of times = once · use of R-type flux (2) Use of Sn-3.0Ag-0.5Cu solder Bath · solder bath temperature = 245°C · dipping time = 5 seconds · the number of times = once · use of R-type flux TA7712P/PG TA7712F/FG Weight DIP20−P−300−2.54A : 2.25 g (Typ.)
