3 Description

The DRV8816 provides a versatile power driver solution with two independent ½-H bridge drivers. The device can drive one brushed DC motor or one winding of a stepper motor, as well as other devices like solenoids. A simple INx/ENx interface allows easy interfacing to controller circuits.

The output stages use N-channel power MOSFETs configured as ½-H-bridges. The DRV8816 is capable of peak output currents up to ±2.8 A and operating voltages up to 38 V. An internal charge pump generates needed gate drive voltages.

A low-power sleep mode is provided which shuts down internal circuitry to achieve very-low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin.

Internal protection functions are provided for UVLO, charge pump fault, OCP, short-to-supply protection, short-to-ground protection, overtemperature warning, and overtemperature shutdown. Fault conditions are indicated through a nFAULT pin

The DRV8816 is packaged in a 16-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br)

Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
POWER AND GROUND
CP1 11 PWR Charge pump switching node Connect a 0.1-µF X7R capacitor rated for VBB between CP1 and CP2
CP2 12 —
GND 4, 13, PPAD PWR Device ground Connect to system ground
VBB 9 PWR Power supply input Connect to main power supply. Bypass to GND with a 0.1-µF ceramic capacitor and a larger bulk capacitor rated for at least the VBB voltage
VCP 14 PWR Charge pump output Connect a 0.1-µF 16-V ceramic capacitor between VCP and VBB
CONTROL
EN1 6 I ½-H bridge enable Logic high enables ½-H bridge output; logic low puts the FETs in HI-Z; internal pull-down
EN2 2
IN1 3 I ½-H bridge control Logic high enables the high-side ½-H bridge FET; logic low enables the low side FET; internal pull-down
IN2 16
nFAULT 1 O Fault indication pin Pulled logic low with fault condition; open-drain output requires an external pull-up. This output is indeterminate in sleep mode
nSLEEP 5 I Device sleep mode Pull logic low to put device into a low-power sleep mode; internal pull-down
OUTPUT
OUT1 7 O ½-H bridge output
OUT2 10 O ½-H bridge output
SENSE 8 O H-bridge low-side connect Connect directly to GND or through a sense resistor to set OCP
VPROPI
VPROPI 15 O Current-proportional output

Table 1. External Components

COMPONENT PIN 1 PIN 2 RECOMMENDED
CVBB VBB GND 0.1-µF ceramic capacitor and a larger bulk capacitor rated for at least the VBB voltage
CVCP VCP VBB 0.1-µF 16-V ceramic capacitor
RnFAULT VCC(1) nFAULT >1 kΩ resistor
RnSLEEP VCC(1) nSLEEP If nSLEEP isn't actively controlled, use a pull-up resistor of less than 20 kΩ
RSENSE SENSE GND Optional low-value resistor. If not used, connect SENSE pin directly to GND.
(1) VCC is not a pin on the DRV8816, but a VCC supply voltage pullup is required.
