TA8470AF

TA8470AF is a kind of low-noise type 3 Phase Bi-direction Motor Driver IC, developed as a 3 Phase Hall motor driver for VTRs (capstan, cylinder), etc.

The features of TA8470AF can be summarized as (1)operating voltage range: VCC=7~17V; (2)output current: IO(MAX) = 1.2A; (3)three phase bi-direction, current control mode; (4)low noise (quasi sinusoidal drive); (5)built-in FG amplifier; (6)low output impedance with class push-pull driver, capable of short brakes (dumping brakes); (7)position detecting circuit (hall input) with high sensitivity : VH =50mVp-p; (8)enclosed in space-saving power flat package; (9)built-in thermal shutdown circuit.

The absolute maximum ratings of TA8470AF are (1)supply voltage VCC: 18V; (2)output current IO: 1.2A; (3)fg output current IFGO/IFGS: 12/14 mA; (4)power dissipation PD: 1.0(Note 1: Without heat sink)/3.2(Note 2: 50×50×1mm Fe board mounting )/5.8(Note 3: Infinite heat sink mounting)W; (5)operating temperature Topr: -30~75°C; (6)storage temperature Tstg: - 55~150°C.
