L6258E
Note:
The number in parenthesis shows the relevant Power Bridge of the circuit. Pins 18, 19, 1
and 36 are connected together.
8VDD (5V)
Supply voltage input for logic circuitry
9
GND
Power ground connection of the internal charge pump circuit
10
VCP1
Charge pump oscillator output
11
VCP2
Input for external charge pump capacitor
12
VBOOT
Overvoltage input for driving of the upper DMOS
13, 31
VS
Supply voltage input for output stage. They are shorted
internally
14
OUT2A
Bridge output connection (2)
15
I0_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 5 on page 12.
16
I1_2
See pin 15
18, 19
PWR_GND
Ground connection. They also conduct heat from die to
printed circuit copper
20, 35
SENSE2, SENSE1 Negative input of the transconductance input amplifier (2, 1)
21
OUT2B
Bridge output connection and positive input of the
tranconductance (2)
22
I3_2
See pin 15
23
I2_2
See pin 15
24
EA_OUT_2
Error amplifier output (2)
25
EA_IN_2
Negative input of error amplifier (2)
26, 28
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
27
SIG_GND
Signal ground connection
29
EA_IN_1
Negative input of error amplifier (1)
30
EA_OUT_1
Error amplifier output (1)
32
I2_1
See pin 3
33
I3_1
See pin 3
34
OUT1B
Bridge output connection and positive input of the
tranconductance (1)
