So it is perfectly suited to interface control IC with Power Switches in low side or half-bridge configuration. The typical application shown figure 1 implements the TD310 in a pulse controlled half-bridge drive. 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 and short-circuit protection as shown in application note n AN461. On Figure 2, TD310 is implemented as a low side driver in a typical 3 phase motor drive. Figure 3 presents a general purpose low side gate drive. In both case, the current amplifier provides interfacing between a sense resistor and an A/D converter.

Typ. 1.5 Max. 2 Unit mA 3/9 TD310 UVLO/stbdy pin functionning modes Due to the wide supply voltage range of the TD310, the UVLO function (Under Voltage Lock Out) is externally adjustable by a resistor bridge. The bridge rate can be calculated in relation with the expected UVLO protection level as follows : VUVLO x R1 =1.2V (where R1 is the lower resistor of the bridge) R1+R2 The internal resistor sets the default UVLO value to 12V (*) and might influence the external bridge rate if the values of the external resistors are too high. The standby threshold value depends of the UVLO value as follows : Vstdby = 0.71.2 VUVLO Both UVLO and stdby functions can be inhibited by connecting the UVLO/stdby pin to VCC+ via a pull up resistor (ex 150k). The following table summarizes the functions of the TD310 : Pin Configuration 16 UVLO/stdby 9/11 5 2/3/4 15/14 /13 6 7/8/10 Sense+/Sense- Enabl In A/B/C Out Alarm Op.

Configuration 2 : UVLO/stdby = L The TD310 is in a low consumption state (standby mode 30A), the buffer outputs are set to low state and the operational amplifier is in high impedance state. Configuration 3 : UVLO/stdby = M The VCC supply voltage is between VUVLO and Vstdby (**). The TD310 remains in a normal consumption state and the operational amplifier is normally functionning but the buffer outputs and the alarm pin are set to low state. (*) If the UVLO level remains unadjusted, it is recommended to bypass the UVLO/stdby pin with a 1nF capacitor. (**) If the supply voltage falls below Vstdby, the TD310 is set in standby mode (configuration 2). 4/9 TD310 TIMING DIAGRAM TIMING 1 Input A/B/C tdH tli tdL Output A/B/C TIMING 2 Input A/B/C Output A/B/C ts tAi Se ns e teL tA Alarm tAi te H Enable Under Volta ge 5/9 TD310 TYPICAL APPLICATIONS Figure 1 : THREE PHASE MOTOR DRIVE 15 V 1 F High Volta ge MCU s ig n a ls TD310 P ulse trans forme r ON P u lse co ntrolle d inp uts OFF 3 P h as e s moto r Leve l co n trolled inp ut CONTROL UNIT e nable 15V inte rru pt a larm AD co nve rter Rse n s e 6/9 TD310 Figure 2 : THREE PHASE MOTOR LOW SIDE DRIVE Vd T1 L6380 T3 T5 L6380 KEYBOARD S T6 P B U F F E R DISP LAY T D 3 1 0 MOTOR L6380 T2 T4 T6 Figure 3 : LOW SIDE DRIVE +1 5 V 1 F Loa d Loa d Loa d Rs ens e 7/9 TD310 PACKAGE MECHANICAL DATA 16 PINS - PLASTIC DIP Dimensions a1 B b b1 D E e e3 F i L Z Min. 0.51 0.77 Millimeters Typ.
