TA8440H/HQ
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8440H/HQ
Full-bridge Driver (H-Switch) for DC Motor
(Driver for Switching between Forward and Reverse Rotation)
The TA8440H/HQ is a full-bridge driver for selecting the forward
and reverse running of a motor with brushes and can control four
modes: forward, reverse, stop and braking.
The motor driving unit and the control unit have a separate
power supply line, and the TA8440H/HQ can also be used as a
stepping motor driver.
Features
z Output current is up to 1.5 A (AVE.) and 3.0 A (PEAK).
z 4 modes of forward, reverse, stop, and braking are available
and a back-electromotive force absorbing diode has been
built-in.
z Thermal shutdown circuit incorporated
z Input is compatible with CMOS.
z Built-in input pull-up resistor. BRAKE = 200 k(typ.)
z Built-in input pull-down resistor. IN, ENABLE = 100 k(typ.)
Weight: 4.04 g (typ.)
The TA8440HQ:
The TA8440HQ is Sn-Ag 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
