DESCRIPTION

The DRV8828 provides an integrated motor driver solution for printers, scanners, and other automated

equipment applications. The device has one H-bridge driver, and can drive one winding of a bipolar stepper

motor or one DC motor. The output driver block consists of N-channel power MOSFET’s configured as a full H-

bridge to drive the motor winding. The DRV8828 is capable of driving up to 3-A of output current (with proper

heatsinking at 24 V and 25°C).

A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is

programmable.

Internal shutdown functions are provided for overcurrent protection, short circuit protection, undervoltage lockout

and overtemperature.

The DRV8828 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).

DRV8828 SLVSA11E – OCTOBER 2009 – REVISED AUGUST 2013 www.ti.com FUNCTIONAL DESCRIPTION PWM Motor Drivers The DRV8828 contains one H-bridge motor driver with current-control PWM circuitry. A block diagram of the motor control circuitry is shown in Figure 1. A bipolar stepper motor is shown, but the driver can also drive a DC motor. Figure 1. Motor Control Circuitry Note that there are multiple VM, ISEN, OUT, and VREF pins. All like-named pins must be connected together on the PCB.

DRV8828 www.ti.com SLVSA11E – OCTOBER 2009 – REVISED AUGUST 2013 The full-scale (100%) chopping current is calculated in Equation 1. VREFX ICHOP = 5¾ · RISENSE (1) Example: If a 0.5-Ω sense resistor is used and the VREFx pin is 3.3 V, the full-scale (100%) chopping current will be 3.3 V / (5 x 0.5 Ω) = 1.32 A. Five input pins (I0 - I4) are used to scale the current in the bridge as a percentage of the full-scale current set by the VREF input pin and sense resistance.
PAGE 10
DRV8828 SLVSA11E – OCTOBER 2009 – REVISED AUGUST 2013 www.ti.com Once the chopping current threshold is reached, the H-bridge can operate in two different states, fast decay or slow decay. In fast decay mode, once the PWM chopping current level has been reached, the H-bridge reverses state to allow winding current to flow in a reverse direction. As the winding current approaches zero, the bridge is disabled to prevent any reverse current flow. Fast decay mode is shown in Figure 2 as case 2.
PAGE 11
DRV8828 www.ti.com SLVSA11E – OCTOBER 2009 – REVISED AUGUST 2013 nRESET and nSLEEP Operation The nRESET pin, when driven active low, resets the internal logic. It also disables the H-bridge drivers. All inputs are ignored while nRESET is active. The nRESET pin has an internal pulldown resistor of 100 kΩ. The nSLEEP pin has an internal pulldown resistor of 1 MΩ. Driving nSLEEP low will put the device into a low power sleep state.

DRV8828 SLVSA11E – OCTOBER 2009 – REVISED AUGUST 2013 www.ti.com THERMAL INFORMATION Thermal Protection The DRV8828 has thermal shutdown (TSD) as described above. If the die temperature exceeds approximately 150°C, the device will be disabled until the temperature drops to a safe level. Any tendency of the device to enter TSD is an indication of either excessive power dissipation, insufficient heatsinking, or too high an ambient temperature.
