DESCRIPTION

The TD310 is designedto driveone, two or three
Power IGBT/MOS and has driving capability for
pulse transformer.So itis perfectlysuited to inter­face control IC with Power Switchesin low side or
half-bridgeconfiguration.

The typicalapplication shown figure 1 implements
the TD310 in a pulse controlled half-bridgedrive.
Positive and negative pulses are applied to the
pulse transformer to charge and discharge the
IGBT/MOS gate capacitance. More sophisticated
secondary circuits provide low impedance gate
drive andshort-circuit protectionas shownin appli­cation note n°AN461.

On Figure2, TD310is implementedas a low side
driverin a typical 3 phase motor drive.

Figure 3 presentsa generalpurposelow side gate
drive.

In both case, the current amplifier provides inter­facing between a senseresistor and anA/D
converter.

INSTRUCTIONS FORUSE

1 - The TD310 supply voltage must be decoupledwith a 1µF min.capacitor.
2 - If theapplicationinvolving TD310 requires maximum output current capability,

this current must be pulsed : pulse width 1µsec, duty cycle 1% at T

TD310

UVLO/stbdypin functionning modes

Due to the wide supply voltage range of the TD310, the UVLO function (Under Voltage Lock Out) is
externallyadjustable by a resistorbridge.

The bridge rate can be calculatedin relation with the expectedUVLO protectionlevel as follows:

R1

UVLO

x

R1

V

The internal resistorsets the defaultUVLO value to 12V(*) and might influencethe external bridge rate if
the valuesof the externalresistors are toohigh.

The standbythreshold value depends of the UVLOvalue as follows :

=1.2V(where R1 is the lowerresistor of thebridge)

Both UVLOand stdby functions can be inhibited by connectingthe UVLO/stdby pin to V
resistor (ex 150kΩ).

Consumption

Configuration 1 : UVLO/stdby= H
The TD310 is in a normal consumption state (1.5mA), the operationalamplifier is normally functionning

and the buffer outputs are determinedby the sensecomparator inputs, the enableinputs and the buffer
inputs.

Configuration 2 : UVLO/stdby= L
The TD310 isin a lowconsumptionstate (standbymode30µA), the bufferoutputs are set to low state and

the operationalamplifieris inhigh impedance state.

Configuration 3 : UVLO/stdby= M
The V

supply voltage is between V

CC

UVLO

and V

(**). The TD310 remains in a normal consumption

stdby

state and the operationalamplifieris normally functionningbut thebuffer outputsand the alarm pin areset
to lowstate.

(*) If the UVLO level remains unadjusted, it isrecommended to bypass the UVLO/stdby pin with a 1nF capacitor.
(**) If the supply voltage falls below V

4/9

, the TD310 isset in standby mode (configuration 2).
