We generally recommend using a capacitor of at least a few hundred μF and rated well above the maximum supply voltage; the required capacitance will be greater if the power supply is poor or far (more than about a foot) from the driver, and it will also depend on other factors like motor characteristics and applied PWM frequency. A through-hole capacitor can be installed directly on the board in the holes labeled VM and GND on the silkscreen ('+' and '−' in the wiring diagram pictures below). The driver includes 8.8 µF of on-board ceramic capacitors, which might be sufficient for brief tests and limited low-power operation, but adding a bigger capacitor is recommended for most applications.\u003c\/p\u003e\n\u003ch3 class=\"clear\"\u003ePWM (IN\/IN) mode\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable class=\"picture_with_caption center wide mceItemTable\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca class=\"noscript-fallback\" href=\"https:\/\/a.pololu-files.com\/picture\/0J13953.1200.jpg?c5520500f8790b1ce171d91086fedc13\" target=\"_blank\"\u003e\u003cimg class=\"wide zoomable\" src=\"https:\/\/a.pololu-files.com\/picture\/0J13953.600.jpg?c5520500f8790b1ce171d91086fedc13\" alt=\"\" data-gallery-pictures='[{\"id\":\"0J13953\",\"caption\":\"\\u003cp\\u003eMinimal wiring diagram for connecting a microcontroller to a DRV8263H Single Brushed DC Motor Driver Carrier in PWM (IN\/IN) control mode.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J13953.98x98.jpg?c5520500f8790b1ce171d91086fedc13\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J13953.600x480.jpg?c5520500f8790b1ce171d91086fedc13\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J13953.1200.jpg?c5520500f8790b1ce171d91086fedc13\",\"longest_side\":1199}]' data-picture-id=\"0J13953\" data-picture-longest_side=\"1199\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cp\u003eMinimal wiring diagram for connecting a microcontroller to a DRV8263H Single Brushed DC Motor Driver Carrier in PWM (IN\/IN) control mode.\u003c\/p\u003e\n\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eWhen the MODE pin is left floating, the driver is set to PWM (IN\/IN) control mode.

A duty cycle of 50% will stop the motor.

The output voltage is about 300 mV\/A by default.\u003c\/p\u003e\n\u003cp\u003eThe DRV8263H-Q1 has the ability to limit the motor current through current chopping: once the IPROPI voltage reaches a set threshold, the driver goes into brake mode (slow decay) for about 30 µs before applying power to drive the motor again. This makes it more practical to use the driver with a motor that might only draw a few amps while running but can draw many times that amount when starting.\u003c\/p\u003e\n\u003cp\u003eThe current limit is affected by both the ITRIP configuration and the current sense sensitivity. By default, the current regulation trip threshold is 3 V; together with the default 300 mV\/A sensitivity, this corresponds to a 10 A current limit. The threshold can be lowered by connecting ITRIP to ground through resistors as described in the datasheet, or current limiting can be disabled entirely by connecting ITRIP directly to ground (although the driver has separate overcurrent protection functionality that remains active). Alternatively, the current limit can be raised by lowering the current sense sensitivity through the addition of an external pull-down resistor on IPROPI in parallel with the 1.5 kΩ already on the board.\u003c\/p\u003e\n\u003ch3\u003eReal-world power dissipation considerations\u003c\/h3\u003e\n\u003cp\u003eThe DRV8263H has overcurrent protection that kicks in at a minimum of 28 A, and the board is configured for a current limit of 10 A by default. However, the chip by itself will overheat at lower currents. In our tests, we found that the chip on our carrier board was able to deliver 10 A for less than a second before its thermal protection kicked in and disabled the motor outputs. The actual current you can deliver will depend on how well you can keep the motor driver cool. The shield’s printed circuit board is designed to help with this by drawing heat out of the motor driver chip.\u003c\/p\u003e\n\u003cp\u003ePWMing the motor will introduce additional heating proportional to the frequency, and the driver’s slew rate setting is also a factor here. For most applications, we recommend connecting the SR pin directly to ground (as shown in the minimal wiring diagrams above) to select the fastest slew rate on the DRV8263H.
