DESCRIPTION
The TD340 integrated circuit allows N-Channel
Power
Mosfets
driving
in
a
full
H-bridge
configuration and is best suited for DC Motor
Control Applications. The four drivers outputs are
designed to allow 25kHz MOSFET switching.
The speed and direction of the motor are to be set
by two pins. Voltage across the motor is controlled
by low side Pulse Width Modulation (PWM). This
PWM feature can be made internally when the
input pin is connected to an analog signal, or it can
be given directly from a digital source.
An internal charge pump allows proper upper
MOS driving for full static operation (100% PWM).
TD340 achieves very low EMI noise thanks to its
balanced charge pump structure and its drivers
moderate slew rate.
To avoid excessive heating due to free wheeling,
appropriate synchronous rectification is achieved
on the corresponding High Side MOSFET.
Moreover,
TD340
integrates
a
5V
voltage
regulator suitable as a power supply output for the
microcontroller, a Reset circuit and a Watchdog
circuit.
Security functions disable the TD340 (MOS off)
when abnormal conditions occur like overvoltage,
undervoltage or CPU loss of control (watchdog).
TD340 withstands transients as met in automotive
field without special protection devices thanks to
its 60V BCD technology.
