7.3.5.2 Internal Memory Interface
The DRV2605 device has six internal-ROM libraries designed by Immersion called TS2200. The first five libraries are specifically tuned for five categories of ERMs operated in open-loop mode (see Table 1). Library 6 is a closed-loop library tuned for LRAs. The library selection occurs through register 0x03 (see the (Address: 0x03) section).

Table 1. ERM Library Table
| LIBRARY | RATED VOLTAGE | OVERDRIVE VOLTAGE | RISE TIME | BRAKE TIME |
|---|---|---|---|---|
| A | 1.3 V | 3 V | 40 ms to 60 ms | 20 ms to 40 ms |
| B | 3 V | 3 V | 40 ms to 60 ms | 5 ms to 15 ms |
| C | 3 V | 3 V | 60 ms to 80 ms | 10 ms to 20 ms |
| D | 3 V | 3 V | 100 ms to 140 ms | 15 ms to 25 ms |
| E | 3 V | 3 V | > 140 ms | > 30 ms |
