TA8401F/FG
TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TA8401F/FG
Functional Bridge Driver
Features
Wide operating supply voltage range:
V
CC
(opr.) = 3.0~15 V
Capsuled 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.)
The TA8401FG 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

・Utmost
care is necessary in the design of the output, V
CC
, V

, and GND lines since the IC may be destroyed by
short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by short-circuiting
between contiguous pins.
