TD340 General 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 toallow 25kHz MOSFET switching.
The speedand directionofthe motor aretobe set by twopins.Voltage across themotor iscontrolled by low side Pulse Width Modulation (PWM). This PWM feature can be made internally when the input pinis connectedtoananalogsignal,or itcan be given directly from a digital source.
An internal charge pump allows proper upper MOS driving for fullstatic 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 HighSide MOSFET.
Moreover, TD340 integrates a 5V voltage regulator suitableasa powersupplyoutput forthe microcontroller, a Reset circuit and a Watchdog circuit.
Security functions disable the TD340 (MOS off) when abnormal conditionsoccur like overvoltage,undervoltage or CPU loss of control (watchdog).
TD340 withstandstransients asmet inautomotive field without special protection devices thanks to its 60V BCD technology.

Notes:
1. The duration of the 60V voltage must be limited to 1 second ifcurrent is drained from the Vout regulator. Supply voltage insteady state must be limitedto ensure that dissipation rating is not exceeded.
2. The magnitude of input and output voltages must never exceed Vbatt+0.3V or 60V, whichever is less, except for H1 and H2: Vbatt+15V or 60V, whichever is less.
