Pin description
N°
Pin
Type
Function
1, 21
GND
Signal ground terminals.
9
OUT1B
Power output Bridge B output 1.
11
OCDB
Open drain
output
Bridge B overcurrent detection and thermal protection pin. An internal open
drain transistor pulls to GND when overcurrent on bridge B is detected or in
case of thermal protection.
12
SENSEB
Power supply
Bridge B source pin. This pin must be connected to power ground directly or
through a sensing power resistor.
13
IN1B
Logic input
Bridge B input 1
14
IN2B
Logic input
Bridge B input 2
15
PROGCLB
R pin
Bridge B overcurrent level programming. A resistor connected between this
pin and ground sets the programmable current limiting value for the bridge B.
By connecting this pin to ground the maximum current is set. This pin cannot
be left non-connected.
16
ENB
Logic input
Bridge B enable. LOW logic level switches OFF all power MOSFETs of
bridge B.
If not used, it has to be connected to +5 V.
17
VBOOT
Supply
voltage
Bootstrap voltage needed for driving the upper power MOSFETs of both
bridge A and bridge B.
19
OUT2B
Power output Bridge B output 2.
20
VSB
Power supply
Bridge B power supply voltage. It must be connected to the supply voltage
together with pin VSA.
22
VSA
Power supply
Bridge A power supply voltage. It must be connected to the supply voltage
together with pin VSB.
23
OUT2A
Power output Bridge A output 2.
24
VCP
Output
Charge pump oscillator output.
25
ENA
Logic input
Bridge A enable. LOW logic level switches OFF all power MOSFETs of
bridge A.
If not used, it has to be connected to +5 V.
26
PROGCLA
R pin
Bridge A overcurrent level programming. A resistor connected between this
pin and ground sets the programmable current limiting value for the bridge A.
By connecting this pin to ground the maximum current is set. This pin cannot
be left non-connected.
27
IN1A
Logic input
Bridge A logic input 1.
28
IN2A
Logic input
Bridge A logic input 2.
29
SENSEA
Power supply
Bridge A source pin. This pin must be connected to power ground directly or
through a sensing power resistor.
30
OCDA
Open drain
output
Bridge A overcurrent detection and thermal protection pin. An internal open
drain transistor pulls to GND when overcurrent on bridge A is detected or in
case of thermal protection.
31
OUT1A
Power output Bridge A output 1.
