8-Bit Serial-Input Protected Latched Driver
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
DD
is cycled or the ENABLE/RESET pin is pulsed high. Current
pulses less than 2µs 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 ; hysteresis of 0.5V is provided.
