TPIC6A595 Resistive Load Operation
A. The word generator has the following characteristics: tr ≤ 10ns, tf ≤ 10ns, tw = 300ns, pulsed repetition rate (PRR) = 5kHz, ZO = 50Ω.
B. CL includes probe and jig capacitance.
C. Write data and read data are valid only when RCK is low

TPIC6A595 Chopping-Mode Characteristics
A. Figure 6-4 illustrates the output current characteristics of the device energizing a load having initially low, increasing resistance, for example, an incandescent lamp. In region 1, chopping occurs and the peak current is limited to IOK. In region 2, output current is continuous. The same characteristics occur in reverse order when the device energizes a load having an initially high, decreasing resistance.
B. Region 1 duty cycle is approximately 2%.

TPIC6A595 Reverse-Recovery-Current Test Circuit and Waveforms of Source-Drain Diode
A. The VGG amplitude and RG are adjusted for di/dt = 20A/µs. A VGG double-pulse train is used to set IF = 0.35A, where t1= 10µs, t2 = 7µs, and t3 = 3µs.
B. The DRAIN terminal under test is connected to the TP K test point. All other terminals are connected together and connected to the TP A test point.
C. IRM = maximum recovery current.

TPIC6A595 Single-Pulse Avalanche Energy Test Circuit and Waveforms
A. † Non-JEDEC symbol for avalanche time.
B. The word generator has the following characteristics: tr ≤ 10ns, tf ≤ 10ns, ZO = 50Ω.
C. Input pulse duration, tw, is increased until peak current IAS = 600mA. Energy test level is defined as EAS = (IAS x V(BR)DSX x tav)/2 = 75mJ.

The single-pulse curve represents measured data. The curves for various pulse durations are based on the following equation:

Equation 1. TPIC6A595

where:

  • Zθ(tw) = the single-pulse thermal impedance for t = tw seconds
  • Zθ(tc) = the single-pulse thermal impedance for t = tc seconds
  • Zθ(tw+tc) = the single-pulse thermal impedance for t = tw + tc seconds
  • d = tw/tc
