Figure 3. Example of code 5 broken into its binary components,

equaling code 4 and code 1.

Note: After blowing, the programming is not reversible, even

after cycling the supply power. Although a register bit field fuse

cannot be reset after it is blown, additional bits within the same

example, if bit 1 (binary 10) has been blown, it is still possible to

blow bit 0. The end result would be binary 11 (decimal code 3).

Locking the Device

After the desired code for each parameter is programmed, the

device can be locked to prevent further programming of any

parameters. See the Lock Mode section for lock pulse sequence.

Additional Guidelines

The additional guidelines in this section should be followed to

ensure the proper behavior of these devices:

• A 0.1 μF blowing capacitor, CBLOW, must be mounted between

the VOUT pin and the GND pin during programming, to ensure

enough current is available to blow fuses.

• The CBLOW blowing capacitor must be replaced in the final

application with a suitable CL. (The maximum load capacitance

is 10 nF for proper operation.) The power supply used for

programming must be capable of delivering at least 26 V and

300 mA. Be careful to observe the tLOW delay time before

powering down the device after blowing each bit.

• The following programming order is recommended:

1. Coarse VOUT(Q)

2. Sens

3. VOUT(Q)

4. LOCK (only after all other parameters have been

programmed and validated, because this prevents any further

programming of the device)
