DRV8912QPWPRQ1

The DRV89xx-Q1 is a series of pin-to-pin compatible integrated multi-channel half-bridge drivers with 4 to 12 half-bridges. This device series features low on-state resistance (RDS(ON)), which can improve thermal performance during high-current operation.

Applications

• HVAC flap DC motors
• Side mirror adjustment and mirror folding
• LED applications
• Multi-brush DC motors and solenoids

Key features

• Independent half-bridge PWM operation
• Configurable for high-side, low-side, and H-bridge load driving
• 8-bit duty cycle resolution
• Integrated protection with per-channel detailed diagnostics via SPI
• nFAULT pin output
• VM undervoltage lockout (UVLO)
• VM overvoltage protection (OVP)
• Logic supply power-on reset (POR)
• Overcurrent protection (OCP)
• Enhanced open-load detection (OLD)
• Thermal warning and thermal shutdown (OTW/OTSD)
• PWM generator programmable via SPI
• These devices can drive brushed DC (BDC) motors or stepper motors in independent, sequential, or parallel mode. The half-bridges are fully controllable to achieve forward, reverse, coast, and brake motor operations
• These devices feature a standard 16-bit 5MHz SPI with daisy-chain capability for full configuration and detailed diagnostics
• Four or eight programmable PWM generators are integrated, depending on the device, to limit current during motor operation or LED dimming control
• The device incorporates numerous protection and diagnostic features, including an nFAULT pin to alert the system when a fault occurs
• The device features a low-current OLD mode for detecting open-load conditions when the nominal load current is small, and a passive OLD mode for offline OLD
• The device also provides comprehensive protection against short-circuit, undervoltage, and overtemperature conditions
