5
D-GND
Lower side internal diode anode connection
6
E1
Constant current control sensing
The motor current is set by the value of the sensing resistor Re connected between the E1 pin and ground.
The current is set according to the following equation : IO = VREF/Re (A)
7
VS1
VS power supply
8
NC
Unused
9
VCC
VCC power supply
10
CR
RC oscillator connection
11
VREF1
Current setting system reference voltage input
VREF1 voltage range : 0 to 0.5V
12
NC
Unused
13
ENABLE1
Output is turned on when ENABLE1 is low, and the output is turned off (operating state) when ENABLE1 is high.
14
PHASE1
Logic level input : phase switching
When PHASE1 = high : Output pin states : OUT1 : high, OUT1- : low.
When PHASE1 = low : Output pin states : OUT1 : low, OUT1- : high.
15
ST
Standby mode setting
When ST = high : the IC operates in normal operating mode.
When ST = low : the IC operates in standby mode. The VS and VCC current drain levels are under 1μA in this mode.
16
NC
Unused
17
1VREG
1V regulator circuit output
The LB11948 includes an internal 1V regulator circuit, and this pin is the output from that circuit. The VREF1 and VREF2
reference voltages can be set by voltage dividing the 1V regulator output.
18
PHASE2
Logic level input : phase switching
When PHASE2 = high : Output pin states : OUT2 : high, OUT2- : low.
When PHASE2 = low : Output pin states : OUT2 : low, OUT2- : high.
19
ENABLE2
Output is turned on when ENABLE2 is low, and the output is turned off (operating state) when ENABLE2 is high.
20
VREF2
Current setting reference voltage input
VREF2 voltage range : 0 to 0.5V
