Pin Description
1
ENB
Inhibit pin (high active ): By driving this pin low, all outputs can be turned off regardless of input
signals. Built-in pull-down resistor (100 k typ.).
2
ROSC
This pin sets the oscillation frequency for the charge pump drive.
Connect a 62 k (typ.) resistor.
3
IN1
Input pin: it controls the power MOSFET connected to UU. Built-in pull-down resistor
(100 k typ.).
4
IN2
Input pin: it controls the power MOSFET connected to VU. Built-in pull-down resistor
(100 k typ.).
5
IN3
Input pin: it controls the power MOSFET connected to WU. Built-in pull-down resistor
(100 k typ.).
6
IN4
Input pin: it controls the power MOSFET connected to UB. Built-in pull-down resistor
(100 k typ.).
7
IN5
Input pin: it controls the power MOSFET connected to VB. Built-in pull-down resistor
(100 k typ.).
8
IN6
Input pin: it controls the power MOSFET connected to WB. Built-in pull-down resistor
(100 k typ.).
9
SGND1
Signal block GND pin: shared internally with pin 11.
10
CP1
Capacitor pin for charge pump.
11
SGND2
Signal block GND pin: shared internally with pin 9.
12
CP2
Capacitor pin for charge pump.
13
VDD
Power supply pin: when under-voltage (5.5 V typ.) is detected, FAULT output goes high. On this
occasion, all outputs are switching normally, and charge pump circuit does not come to a stop.
14
FAULT
Diagnosis output pin: when under-voltage (5.5 V typ.) is detected, FAULT output goes high.
High-side/low-side arm shorting mode, FAULT output goes high and all outputs are shut down.
Circuit configuration is N-ch open drain.
15
WB
Drives the power MOSFET connected to the low side of the W phase.
16
PGND1
Power block GND pin: shared internally with pin 18.
17
VB
Drives the power MOSFET connected to the low side of the V phase.
18
PGND2
Power block GND pin: shared internally with pin 16.
19
UB
Drives the power MOSFET connected to the low side of the U phase.
20
UU
Drives the power MOSFET connected to the high side of the U phase.
21
VU
Drives the power MOSFET connected to the high side of the V phase.
22
WU
Drives the power MOSFET connected to the high side of the W phase.
23
CPV
Final stage capacitor pin for the charge pump.
24
COSC
This pin sets the oscillation frequency for the charge pump drive.
Connect a 270pF (typ.) capacitor.
