Fonctionnalités et applications
The MIC59P60YN serial-input latched driver is a high-voltage (80 V), high-current (500 mA) 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 500 mA and integral diodes for inductive load transient suppression with a minimum output breakdown voltage rating of 80 V (50 V sustaining). The drivers can be operated with a split supply, where the negative supply is down to –20 V and may be paralleled for higher load current capability. Using a 5 V logic supply, the MIC59P60 will typically operate at better than 5 MHz. With a 12 V logic supply, significantly higher speeds are obtained. The CMOS inputs are compatible 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 VDD is cycled or the ENABLE/RESET pin is pulsed high. Current pulses less than 2 µs 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 VDD; hysteresis of 0.5 V is provided.
