TA7733F/FG
TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TA7733F/FG
Functional Bridge Driver
The TA7733 is a low-voltage bridge driver IC offering four modes:
forward rotation, reverse rotation, stop, and brake.
Features
Wide operating supply voltage range:
V
CC (opr.)
= 1.8~15 V
Housed in a flat package (16-pin)
Forward and reverse rotation, stop and brake modes are
available by means of rotation control signals.
High efficiency is obtained
Can be used as an interface driver.
Weight: 0.14 g (typ.)
Block Diagram
The TA7733FG 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
*number of times = once
*use of R-type flux
