DESCRIPTION

The TD340 integrated circuit allows N-Channel

TD340ID

-40°C, +125°C

•

Power Mosfets driving in

full H-bridge

D = Small Outline Package (SO) - also available in Tape & Reel (DT)

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.
