Block diagram and pin description

VNH7100AS

6/38

DocID028092 Rev 4

Figure 2. Configuration diagram (top view)

Fault detection

Signalizes the abnormal behavior of the switch through

MultiSense pin.

Power limitation

Limits the power dissipation of the high-side driver inside

safe range in case of short to ground condition.

Table 3. Pin definitions and functions

Pin N°

Symbol

Function

1, 16

GNDA

Source of low-side switch A

2, 15

OUTA

Source of high-side switch A / drain of low-side switch A

3INA

Clockwise input

4, 5, 12

VCC

Power supply voltage

6INB

Counter clockwise input

7, 10

OUTB

Source of high-side switch B / drain of low-side switch B

8, 9

GNDB

Source of low-side switch B

11

PWM

Voltage controlled input pin with hysteresis, CMOS compatible. Gates

of low-side FETS get modulated by the PWM signal during their on

phase allowing speed control of the motor. Active high.

13

CS

Multiplexed analog sense output pin; it delivers a current proportional

to the motor current.

14

SEL0

Active high compatible with 3 V and 5 V CMOS outputs pin; in

combination with INA, INB, it addresses the CurrentSense information

delivered to the micro according to the operative truth table.
