Table 5-1 Pin Functions
PIN TYPE DESCRIPTION
NAME NO.
CP1 10 — Charge pump switching node. Connect a X7R, 0.1-μF, VBB-rated ceramic capacitor from CP1 to CP2.
CP2 11 —
ENABLE 4 I Enables OUTA and OUTB drivers
GND 2 PWR Ground
12
MODE 1 16 I Mode logic input
MODE 2 5 I Mode 2 logic input
nFAULT 15 OD Fault indication. Pulled logic low with fault condition; open-drain output requires an external pullup resistor.
nSLEEP 3 I Sleep mode input. Logic high to enable device; logic low to enter low-power sleep mode; internal pulldown resistor.
OUTA 6 O DMOS full-bridge output positive. H-Bridge output A
OUTB 9 O DMOS full-bridge output negative. H-Bridge output B
PHASE 1 I Phase logic input for direction control
SENSE 7 IO Sense power return
VBB 8 PWR Driver supply voltage. Bypass to GND with 0.1-μF ceramic capacitors plus a bulk capacitor rated for VBB.
VCP 13 — Charge pump reservoir capacitor pin. Connect a X7R, 0.1-μF, 16-V ceramic capacitor to VBB.
VPROPI 14 O Winding current proportional voltage output
Thermal pad — Exposed pad for thermal dissipation; connect to GND pins.
