Pin Functions
| PIN | I/O(1) | DESCRIPTION | EXTERNAL COMPONENTS OR CONNECTIONS |
|
|---|---|---|---|---|
| NAME | NO. | |||
| POWER AND GROUND | ||||
| GND | 5, 12, PowerPAD™ | — | Device ground | All pins must be connected to GND. |
| VM | 1 | — | Device power supply | Connect to motor supply (8.2 V - 40 V). |
| CONTROL | ||||
| LATCH | 11 | I | Latch input | Rising edge latches shift register to output stage, falling edge latches fault data into output shift register – internal pulldown |
| nENBL | 8 | I | Enable input | Active low enables outputs – internal pulldown |
| RESET | 9 | I | Reset input | Active-high reset input initializes internal logic – internal pulldown |
| SCLK | 13 | I | Serial clock | Serial clock input – internal pulldown |
| SDATIN | 14 | I | Serial data input | Serial data input – internal pulldown |
| SDATOUT | 15 | OD | Serial data output | Serial data output; push-pull structure; see serial interface section for details |
| STATUS | ||||
| nFAULT | 16 | OD | Fault | Logic low when in fault condition (overtemperature, overcurrent, open load) - open-drain output |
| OUTPUT | ||||
| OUT1 | 3 | O | Output 1 | Connect to load 1 |
| OUT2 | 4 | O | Output 2 | Connect to load 2 |
| OUT3 | 6 | O | Output 3 | Connect to load 3 |
| OUT4 | 7 | O | Output 4 | Connect to load 4 |
| VCLAMP | 2 | — | Output clamp voltage | Connect to VM supply, or zener diode to VM supply |
(1) Directions: I = input, O = output, OD = open-drain output.
