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

Note: In Stop mode, all outputs of La+ through Lc+ and La− through Lc− are disabled.
In Break mode, outputs of La+ through Lc+ are enabled. (Source mode)
(3) Output Circuitry
As shown in the block diagram, the high-side outputs come from the emitters of Darlington-connected PNP
and NPN transistors, and the low-side outputs are open-collectors of NPN transistors.
Connect external transistors in the same manner as shown in the application circuit.
(4) Position Sensor Iinputs
The input voltage swing should be between 20 mVPP and 500 mVPP.
20 mVpp – 500 mVpp
Waveforms of the Hb and Hc input signals
behave the same.
