DescriptionThe DRV8842 provides an integrated motor driver
solution for printers, scanners, and other automated
equipment applications. The device has one H-bridge
driver, andis intendedto drive one DC motor, one
coilofa stepper motor,or other loads. The output
driver block consistsof N-channel power MOSFETs
configuredas an H-bridge. The DRV8842 can supplyto 5-A peakor 3.5-A RMS output current (with
proper heatsinkingat24V and 25°C).
Separate inputsto independently control each halfof
the H-bridge are provided.
Internal shutdown functions are provided for
overcurrent protection, short-circuit protection,
undervoltage lockout, and overtemperature.
TheDRV8842 is available ina 28-pin HTSSOP
package with PowerPAD™ (Eco-friendly: RoHS& no
Sb/Br).
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe datasheet.
