DESCRIPTION

The DRV8835 provides an integrated motor driver solution for cameras, consumer products, toys, and other low-

voltage or battery-powered motion control applications. The device has two H-bridge drivers, and can drive two

DC motors or one stepper motor, as well as other devices like solenoids. The output driver block for each

consists of N-channel power MOSFET’s configured as an H-bridge to drive the motor winding. An internal charge

pump generates needed gate drive voltages.

The DRV8835 can supply up to 1.5-A of output current per H-bridge. It operates on a motor power supply voltage

from 0 V to 11 V, and a device power supply voltage of 2 V to 7 V.

PHASE/ENABLE and IN/IN interfaces can be selected which are compatible with industry-standard devices.

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage

lockout and overtemperature.

The DRV8835 is packaged in a tiny 12-pin WSON package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).

DRV8835 www.ti.com SLVSB18D – MARCH 2012 – REVISED JANUARY 2014 FUNCTIONAL DESCRIPTION Bridge Control Two control modes are available in the DRV8835: IN/IN mode, and PHASE/ENABLE mode. IN/IN mode is selected if the MODE pin is driven low or left unconnected; PHASE/ENABLE mode is selected if the MODE pin is driven to logic high. The following tables show the logic for these modes. Table 2.

DRV8835 SLVSB18D – MARCH 2012 – REVISED JANUARY 2014 www.ti.com Undervoltage Lockout (UVLO) If at any time the voltage on the VCC pins falls below the undervoltage lockout threshold voltage, all circuitry in the device will be disabled, and internal logic will be reset. Operation will resume when VCC rises above the UVLO threshold.

DRV8835 SLVSB18D – MARCH 2012 – REVISED JANUARY 2014 www.ti.com THERMAL INFORMATION Thermal Protection The DRV8835 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 thermal shutdown is an indication of either excessive power dissipation, insufficient heatsinking, or too high an ambient temperature.
