Application Information

1. THERMAL SHUT DOWN CIRCUIT

When Ta = 25

°C, Q2 & Q3 are Turned-off and output stage operates normally.

When Ta = 165

°C, Q2 & Q3 Turn-on and it turns-off the output stage.

∴ T.S.D: 330mV / 2mV = 165°C

2. LOGIC INPUT & OUTPUT TABLE

INPUT High is above 2.0V.

INPUT Low is below 0.7V.

*Low : All Power TRs are off-state.

But internal Bias makes output Voltage low state.
