TA7745P/PG/F/FG
TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TA7745P/PG, TA7745F/FG
3-Phase Full-Wave (Half-Wave) Brushless DC Motor Driver IC
Features
TA7745P/PG
Three-phase, full-wave (and half-wave) driving
Voltage control system
Forward rotation, reverse rotation, and stop can be controlled
using only one pin
High efficiency is obtained.
Housed in a flat package (type F/FG only)
Operating voltage range
: VCC = 4.0 to 15 V
VS = 2 to 15 V
High sensitivity of position sensing inputs, having a hysteresis
: VH = 20 mVp−p (typ.)
Output current
TA7745F/FG
: IO (max) = 1.0 A
Built-in thermal shutdown circuit
The TA7745PG/FG is a Pb-free product.
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
