MIC4807

General Description

The MIC4807 is an 80V, 8-channel, addressable low side

driver with latches and TTL/CMOS compatible logic inputs.

Each logic input is composed of a comparator with a 1.4V

bandgap-derived reference serving as the trip point. The

addresses (A

internal 50 A pull-up current source, while the Output Enable

(OE), Chip Select (CS), and Clear logic inputs have an

internal 75 A pull-down sink. If the logic lines to the MIC4807

are severed, these currents guarantee that the outputs will

turn OFF.

Individual latches in the MIC4807 are selected by a binary

address presented at inputs A

directed to the addressed latch while CS is held low, allowing

an individual output to be pulse-width modulated. When CS

is set high again, the last Data-in is stored in the latch. If Data-

in = "1", the addressed output is turned on, and if Data-in = "0",

the addressed output is turned off.

Information presented to Data-in and the address inputs is

transferred to the latches while CS is pulled low.
