MIC59P60

General Description

The MIC59P60 serial-input latched driver is a high-voltage

(80V), high-current (500mA) integrated circuit comprised of

eight CMOS data latches, a bipolar Darlington transistor

driver for each latch, and CMOS control circuitry for the

common CLEAR, STROBE, CLOCK, SERIAL DATA INPUT,

and OUTPUT ENABLE functions. Similar to the MIC5842,

additional protection circuitry supplied on this device includes

thermal shutdown, under voltage lockout (UVLO), and over-

current shutdown.

The bipolar/CMOS combination provides an extremely low-

power latch with maximum interface flexibility. The MIC59P60

has open-collector outputs capable of sinking 500mA and

integral diodes for inductive load transient suppression with

a minimum output breakdown voltage rating of 80V (50V

sustaining). The drivers can be operated with a split supply,

where the negative supply is down to –20V and may be

paralleled for higher load current capability.

Using a 5V logic supply, the MIC59P60 will typically operate

at better than 5MHz. With a 12V logic supply, significantly

higher speeds are obtained. The CMOS inputs are compat-

ible with standard CMOS, PMOS, and NMOS circuits. TTL

circuits may require pull-up resistors. By using the serial data

output, drivers may be cascaded for interface applications

requiring additional drive lines.

Each of these eight outputs has an independent over current

shutdown of 500 mA. Upon over-current shutdown, the

affected channel will turn OFF and the flag will go low until V

is cycled or the ENABLE/RESET pin is pulsed high. Current

pulses less than 2 s will not activate current shutdown.

Temperatures above 165 C will shut down the device and

activate the error flag. The UVLO circuit prevents operation

at low V
