These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

I/O DESCRIPTION
NAME NO.
AGND 18, 19 Analog ground terminal
Bootstrap terminal for high-side gate drive of negative BTL output (connect a 0.22-mF capacitor with a 51-Ω
BSN 8 I
resistor in series from OUTN to BSN)
Bootstrap terminal for high-side gate drive of positive BTL output (connect a 0.22-mF capacitor with a 51-Ω
BSP 17 I
resistor in series from OUTP to BSP)
BYPASS 22 I Connect 1-mF capacitor to ground for BYPASS voltage filtering
COSC 21 I Connect a 220-pF capacitor to ground to set oscillation frequency
GAIN0 3 I Bit 0 of gain control (see Table 1 for gain settings)
GAIN1 4 I Bit 1 of gain control (see Table 1 for gain settings)
INN 1 I Negative differential input
INP 2 I Positive differential input
OUTN 10, 11 O Negative BTL output, connect Schottky diode from PGND to OUTN for short-circuit protection
OUTP 14, 15 O Positive BTL output, connect Schottky diode from PGND to OUTP for short-circuit protection
PGND 6, 12, 13 Power ground
PV
CC
9, 16 I High-voltage power supply (for output stages)
ROSC 20 I Connect a 120-kΩ resistor to ground to set oscillation frequency
SHUTDOWN 5 I Shutdown terminal (negative logic), TTL compatible, 21-V compliant
V
CC
24 I Analog high-voltage power supply
VCLAMP 7 O Connect 1-mF capacitor to ground to provide reference voltage for H-bridge gates
VREF 23 O 5-V internal regulator for control circuitry (connect a 0.1-mF to 1-mF capacitor to ground)
Connect to AGND and PGND – should be star point for both grounds. Internal resistive connection to AGND.
Thermal pad – – Thermal vias on the PCB should connect this pad to a large copper area on an internal or bottom layer for the
best thermal performance. The PAD must be soldered to the PCB for mechanical reliability.
