OC_CONFIG_05

Description

OUT 5 configuration and H-Bridge 2 diagnostic time

[31:28] C: Command 5

0100

[27] R/W: Bit to read/write configuration

0: Write & request read

1: Request read only

[26:25] HB2_DEAD_TIME: CH-bridge2 dead time to avoid cross conduction

00: 1 µs

01: 2 µs

10: 4 µs

11: 8 µs

[24] HB2_TDIAG_EXT_CONFIG: Selection of tdiag timers for H-bridge 2. This function only applies when HB2_config = 1

(command 8)

0: H-bridge tdiag timers for HB2. The programmed TDIAG_CONFIG_05 will be extended to

CH6, CH7 and CH8.

1: Standard tdiag timers for HB2. The programmed TDIAG_CONFIG_05 is valid only for CH5,

while CH6, CH7 and CH8 must be set individually.

[23:22] TDIAG_CONFIG_05:

H-bridge 2 OFF state diagnostic blanking/filter timer. This values are valid only when HB2_tdiag_ext_config = 0 & HB2_config

= 1

00: 11.2 µs

01: 28.9 µs

10: 40 µs

11: 51.2 µs

OFF state diagnostic blanking/filter timer for output 05. It has no effect if HB2_config = 1 & HB2_tdiag_ext_config = 1

00: 25.6 µs

01: 61.2 µs

10: 105.6 µs

11: 150 µs
