Pin Descriptions

ICd (Pin 1 ) : A +2.5V DC offset used for differential output reading of ICo.

ICo (Pin 2): Hall current sensor output for phase C. The output can be measured between Pin2 and Pin 1

differentially. Zero current corresponds to zero output, current entering Phase C pins will produce positive output

voltage at Pin2, and current out of Phase C pins will produce negative output voltage at Pin2. Also, the output can

be measured as single ended between Pin2 and Pin19. In this case zero current will correspond to 2.5V output,

current entering Phase C pins will produce positive output voltage above 2.5V, and current out of Phase C pins will

produce positive output voltage below 2.5V.The sensitivity of this sensor is 0.018V/A.

IBd (Pin 3): A +2.5V DC offset used for differential output reading of IBo.

IBo (Pin 4): Hall current sensor output for phase B. The output can be measured between Pin4 and Pin 3

differentially. Zero current corresponds to zero output, current entering Phase B pins will produce positive output

voltage at Pin4, and current out of Phase B pins will produce negative output voltage at Pin4. Also, the output can

be measured as single ended between Pin4 and Pin19. In this case zero current will correspond to 2.5V output,

current entering Phase B pins will produce positive output voltage above 2.5V, and current out of Phase B pins will

produce positive output voltage below 2.5V. The sensitivity of this sensor is 0.018V/A.

IAd (Pin 5): A +2.5V DC offset used for differential output reading of IAo.

IAo (Pin 6 ): Phase A hall current sensor output. The output can be measured between Pin6 and Pin 5 differentially.

Zero current corresponds to zero output, current entering Phase A pins will produce positive output voltage at Pin6,

and current out of Phase A pins will produce negative output voltage at Pin6. Also, the output can be measured as

single ended between Pin6 and Pin19. In this case zero current will correspond to 2.5V output, current entering

Phase A pins will produce positive output voltage above 2.5V, and current out of Phase A pins will produce positive

output voltage below 2.5V. The sensitivity of this sensor is 0.018V/A.

TCo (Pin 7 ): An analog output of case temperature sensor. The sensor output gain is 6.25mV/

offset. This sensor can measure both positive and negative

Ω. The

internal block diagram of the temperature sensor is shown in Fig. 6.

The output voltage reading vs temperature will be:

TCo = + 0.58V at Tc= +25

TCo = + 1.205V at Tc= +125

TCo = + 0.174V at Tc= -40

LinA (Pin 8) : An isolated drive input for Low-side IGBT of Phase A.
