Ground connection (1). They also conduct heat from die to printed circuit copper.
These TTL compatible logic inputs set the direction of current flow through the load. A
high level causes current to flow from OUTPUT A to OUTPUT B.
Logic input of the internal DAC (1). The output voltage of the DAC is a percentage of the
Vref voltage applied according to the thruth table of page 7
See pin 3
Bridge output connection (1)
Disables the bridges for additional safety during switching. When not connected the
bridges are enabled
Triangular wave generation circuit capacitor. The value of this capacitor defines the output
switching frequency
Supply Voltage Input for logic circuitry
Power Ground connection of the internal charge pump circuit
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
Bridge output connection (2)
Logic input of the internal DAC (2). The output voltage of the DAC is a percentage of the
VRef voltage applied according to the truth table of page 7
See pin 15
Ground connection. They also conduct heat from die to printed circuit copper
Negative input of the transconductance input amplifier (2, 1)
Bridge output connection and positive input of the tranconductance (2)
See pin 15
See pin 15
Error amplifier output (2)
Negative input of error amplifier (2)
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
Signal ground connection
Negative input of error amplifier (1)
Error amplifier output (1)
See pin 3
