Behavioural mixed-signal modelDRV8833PWPRdrv8833
DRV8833 dual H-bridge motor driver
Two MOSFET H-bridges for 2.7–10.8 V, 1.5 A RMS per bridge: on-resistance 200 mΩ high side + 160 mΩ low side, body diodes. xIN1/xIN2: 10 forward, 01 reverse, 11 brake, 00 coast. A sense resistor on xISEN limits the current to 200 mV / R (50 kHz chopping, slow decay); tie xISEN to GND without current control. nSLEEP high enables the chip (1 ms wake-up). Overcurrent above about 3.3 A switches the bridge off for 1.35 ms and pulls nFAULT low.
