Description  
1
2
(Percent Fast Decay) The analog input used to set the current-decay mode.  
REF  
(VREF) The voltage at this input (along with the value of RS and the states of DAC inputs  
D0, D1, and D2) set the peak output current.  
3
RC  
The parallel combination of external resistor RT and capacitor CT set the off time for the  
PWM current regulator. CT also sets the blanking time.  
4-5  
GROUND  
Return for the logic supply (VCC) and load supply (VBB); the reference for all voltage  
measurements.  
6
7
LOGIC SUPPLY (VCC) Supply voltage for the logic circuitry. Typically = 5 V.  
PHASE  
D2  
The PHASE input determines the direction of current in the load.  
(DATA2) One-of-three (MSB) control bits for the internal digital-to-analog converter.  
(DATA1) One-of-three control bits for the internal digital-to-analog converter.  
One-of-two output load connections.

OUTA  
SENSE  
Connection to the sink-transistor emitters. Sense resistor RS is connected between this  
point and ground.  
12-13  
GROUND  
Return for the logic supply (VCC) and load supply (VBB); the reference for all voltage  
measurements.  
14  
15  
16  
D0  
(DATA0) One-of-three (LSB) control bits for the internal digital-to-analog converter.  
One-of-two output load connections.  
OUTB  
LOAD SUPPLY (VBB) Supply voltage for the load.
