Functional description
5.14
Test condition for all propagation times
(*) Measured at a transition from High impedance (Bridge off) to bridge on. (Reversing polarity takes about 1ms
longer because the bridge first turns off before turning on in reverse direction).
Table of bits
bit5,bit4:
current range of bridge A (Outputs A1 and A2)
bit3:
polarity of bridge A
bit2,bit1:
current range of bridge B (Outputs B1 and B2)
bit0:
polarity of bridge B
bit7,bit6:
Error1 and Error 2
Table 8.
Test condition for all propagation times
(unless otherwise specified) HIGH
≥ 3V; LOW ≤ 0.8V; t
r, tf = 10ns, Enable: ENN Low <
0.8V, ENN High > VCC -0.8V
