VDD (5V)

GND

Supply voltage input for logic circuitry

Power ground connection of the internal charge pump circuit

VCP1

VCP2

VBOOT

VS

Charge pump oscillator output

Input for external charge pump capacitor

Overvoltage input for driving of the upper DMOS

Supply voltage input for output stage. They are shorted

internally

OUT2A

Bridge output connection (2)

Logic input of the internal DAC (2). The output voltage of the

I0_2

DAC is a percentage of the VRef voltage applied according

to the truth Table 5 on page 12.

I1_2

PWR_GND

See pin 15

Ground connection. They also conduct heat from die to

printed circuit copper

SENSE2, SENSE1 Negative input of the transconductance input amplifier (2, 1)

OUT2B

Bridge output connection and positive input of the

tranconductance (2)

I3_2

I2_2

EA_OUT_2

Error amplifier output (2)

EA_IN_2

Negative input of error amplifier (2)

VREF2, VREF1

Reference voltages for the internal DACs, determining the

output current value. Output current also depends on the

logic inputs of the DAC and on the sensing resistor value

SIG_GND

Signal ground connection

EA_IN_1

Negative input of error amplifier (1)

EA_OUT_1 Error amplifier output (1)

I2_1
