General Description
The MIC59P50 parallel-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, and OUTPUT ENABLE func-
tions. Similar to the MIC5801, additional protection circuitry
supplied on this device includes thermal shutdown, under
voltage lockout (UVLO), and over-current shutdown.
The bipolar/MOS combination provides an extremely low-
power latch with maximum interface flexibility. The MIC59P50
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 above V
(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 MIC59P50 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.
Each of these eight outputs has an independent over-current
shutdown at 500 mA. Upon 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 2
μ
s will not activate over-current shutdown.
Temperatures above 165
°
C will shut down the device and
activate the open collector FLAG output at pin 1. The UVLO
circuit disables the outputs at low V
DD
; hysteresis of 0.5V is
provided.
