Pin Definitions and Functions
Pin No.
Function
1, 2, 23, 24
Digital control inputs
I
X0,
I
X1
for the magnitude of the
current
of the
particular phase.
3
Input Phase 1
; controls the current through phase winding 1. On
H-potential the phase current flows from Q11 to Q12, on L-potential in
the reverse direction.
Ground
; all pins are connected internally.
5, 6, 7, 8, 17,
18, 19, 20
4
Oscillator
; works at approx. 25 kHz if this pin is wired to ground across
2.2 nF.
Resistor
R
1
for sensing the current in phase 1.
Push-pull outputs Q11, Q12
for phase 1 with integrated free-wheeling
diodes.
Supply voltage
; block to ground, as close as possible to the IC, with a
stable electrolytic capacitor of at least 10
μ
F in parallel with a ceramic
capacitor of 220 nF.
Logic supply voltage
; either supply with 5 V or connect to +
V
S
across
a series resistor. A Z-diode of approx. 7 V is integrated. In both cases
block to ground directly on the IC with a stable electrolytic capacitor of
10
μ
F in parallel with a ceramic capacitor of 100 nF.
Push-pull outputs Q22, Q21
for phase 2 with integrated free-wheeling
diodes.
Resistor
R
2
for sensing the current in phase 2.
Inhibit input
; the IC can be put on standby by low potential on this pin.
This reduces the current consumption substantially.
Input phase 2
; controls the current flow through phase winding 2. On
H-potential the phase current flows from Q21 to Q22, on L potential in
the reverse direction.
