DESCRIPTION

The DRV8833 provides a dual bridge motor driver solution for toys, printers, and other mechatronic applications.

The device has two H-bridge drivers, and can drive two DC brush motors, a bipolar stepper motor, solenoids, or

other inductive loads.

The output driver block of each H-bridge consists of N-channel power MOSFET’s configured as an H-bridge to

drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current.

With proper PCB design, each H-bridge of the DRV8833 is capable of driving up to 1.5-A RMS (or DC)

continuously, at 25°C with a VM supply of 5 V. It can support peak currents of up to 2 A per bridge. Current

capability is reduced slightly at lower VM voltages.

Internal shutdown functions with a fault output pin are provided for over current protection, short circuit

protection, under voltage lockout and overtemperature. A low-power sleep mode is also provided.

The DRV8833 is packaged in a 16-pin HTSSOP or QFN package with PowerPAD™ (Eco-friendly: RoHS & no

Sb/Br).

DRV8833 SLVSAR1B – JANUARY 2011 – REVISED AUGUST 2011 www.ti.com nSLEEP Operation Driving nSLEEP low will put the device into a low power sleep state. In this state, the H-bridges are disabled, the gate drive charge pump is stopped, all internal logic is reset, and all internal clocks are stopped. All inputs are ignored until nSLEEP returns inactive high. When returning from sleep mode, some time (up to 1 ms) needs to pass before the motor driver becomes fully operational.

DRV8833 SLVSAR1B – JANUARY 2011 – REVISED AUGUST 2011 www.ti.com APPLICATIONS INFORMATION Parallel Mode The two H-bridges in the DRV8833 can be connected in parallel for double the current of a single H-bridge. The internal dead time in the DRV8833 prevents any risk of cross-conduction (shoot-through) between the two bridges due to timing differences between the two bridges. The drawing below shows the connections. Figure 3.

DRV8833 SLVSAR1B – JANUARY 2011 – REVISED AUGUST 2011 www.ti.com THERMAL INFORMATION Maximum Output Current In actual operation, the maximum output current achievable with a motor driver is a function of die temperature. This in turn is greatly affected by ambient temperature and PCB design.
