Texas Instruments · Brushed DC motor driver · HTSSOP-16
Single H-bridge driver for one brushed DC motor from an 8 to 36 V supply, delivering up to 2.8 A. A PHASE pin sets direction and ENABLE drives PWM, while a SENSE pin plus VPROPI give a proportional current-sense output for torque control, and an nFAULT flag reports overcurrent, overtemperature, and undervoltage. An internal charge pump (CP1/CP2/VCP) drives the high-side gates, and nSLEEP powers it down. The PowerPAD carries heat into the board. A full-featured single-motor driver.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | nFAULT | output | Fault indication. Pulled logic low with fault condition. Open-drain output requires an external pullup resistor. VOL = 0.4 V max at Isink = 1 mA. |
| 2 | MODE1 | input | Mode 1 logic input. Combined with MODE2 selects the decay/mode behavior of the H-bridge. |
| 3 | PHASE | input | Phase logic input. Controls the direction of the H-bridge output. Logic-level input referenced to VDD (0-5.5 V). |
| 4 | GND | power_in | Device ground. |
| 5 | nSLEEP | input | Sleep-mode input. Logic high enables the device; logic low enters low-power sleep mode. Internal pulldown resistor. VIH = 2.7 V, VIL = 0.8 V. |
| 6 | ENABLE | input | Enable logic input. Set high to enable the H-bridge; can also be pulsed for PWM current control (0-100 kHz). |
| 7 | OUT+ | output | DMOS H-bridge output. Connect to one motor terminal. Rated ±2.8 A peak, RDS(on) ~0.4 Ω typical. |
| 8 | SENSE | bidirectional | Sense power return. Connect low-side H-bridge return through a sense resistor (e.g. 0.2 Ω) to ground; internally sensed to drive VPROPI current-monitor output. VSense range -500 to +500 mV; VTRP = 500 mV. |
| 9 | VBB | power_in | Driver supply voltage, 8-36 V (abs-max 40 V). Bypass to GND with 0.1-µF ceramic capacitors plus a bulk capacitor rated for VBB. |
| 10 | OUT- | output | DMOS H-bridge output. Connect to the other motor terminal. Rated ±2.8 A peak, RDS(on) ~0.4 Ω typical. |
| 11 | CP1 | passive | Charge pump switching node. Connect a 0.1-µF X7R ceramic capacitor rated for VBB between CP1 and CP2. |
| 12 | CP2 | passive | Charge pump switching node. Connect a 0.1-µF X7R ceramic capacitor rated for VBB between CP1 and CP2. |
| 13 | GND | power_in | Device ground. |
| 14 | VCP | passive | Charge pump reservoir capacitor pin. Connect an X7R, 0.1-µF, 16-V ceramic capacitor to VBB. Charge pump voltage abs-max VBB+17 V. |
| 15 | VPROPI | output | Voltage output proportional to winding (motor) current, driven by an internal differential amplifier with gain DAGain = 5 V/V (over Sense = 0.1-0.4 V). Suitable for feeding an external ADC for current monitoring. |
| 16 | MODE2 | input | Mode 2 logic input. Combined with MODE1 selects the decay/mode behavior of the H-bridge. |
| 17 | PowerPAD | power_in | Exposed pad for thermal dissipation. Connect to ground. |
