TA7289P/F/FG
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA7289P,TA7289F/FG
PWM STEPPING MOTOR DRIVER
The TA7289P, TA7289F/FG are PWM solenoid driver designed
especially for use high efficiency stepping motor control.
It consist of 1.5A peak current drive capable output full bridge
driver, oscillation circuit for PWM switching, 4bit D−A for output
current control and TTL compatible input circuit.
FEATURES
z Wide Range of Operating Voltage
: VCC (opr.) Min. = 6~27 V
z High Current Capability: IO Max = 1.5 A (PEAK)
z LS−TTL Compatible Control Inputs (IN A, IN B)
z Few External Components Required.
z Build−in 4bit DAC.
TA7289F/FG
The TA7289FG is a Pb-free product.
The TA7289P is Sn plated product including Pb.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230°C
*dipping time = 5 seconds
*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
