General Description
The MIC58P42 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 STROBE, CLOCK, SERIAL DATA INPUT, and
OUTPUT ENABLE functions. Similar to the MIC5842, addi-
tional 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 MIC58P42
has open-collector outputs capable of sinking 500 mA 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.
With a 5V logic supply, the MIC58P42 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 detection, the
affected channel will turn OFF until V
is cycled or the
ENABLE/RESET pin is pulsed high. Current pulses less than
2
μ
s will not activate current shutdown. Temperatures above
165
°
C will shut down the device. The UVLO circuit prevents
operation at low V
DD
; hysteresis of 0.5V is provided. See the
MIC59P60 for a similar device that additionally provides an
error flag output.
