1 TC4403 1.5A HIGH-SPEED, FLOATING LOAD DRIVER FEATURES s s s s s s s Low Quiescent Current ......................... 300µA Max Capacitive Inputs With 300mV Hysteresis Both Inputs Must Be Driven to Drive Load Low Output Leakage High Peak Current Capability Fast Output Rise Time Outputs Individually Testable GENERAL DESCRIPTION The TC4403 is a modified version of the TC4425 driver, intended to drive floating or isolated loads requiring highcurrent pulses. The load is intended to be connected between the outputs without other reference to supply or ground. Then, only when both logic inputs and the VDD input are energized, is power supplied to the load. This construction allows the implementation of a wide variety of redundant input controllers. The low OFF-state output leakage and independence of the two half-circuits permit a wide variety of testing schemes to be utilized to assure functionality. The high peak current capability, short internal delays, and fast output rise and fall times ensure that sufficient power will be available to the load when it is needed. The TTL and CMOS compatible inputs allow operation from a wide variety of input devices. The ability to swing the inputs negative without affecting device performance allows negative biases to be placed on the inputs for greater safety. In addition, the capacitive nature of the inputs allows the use of series resistors on the inputs for extra noise suppression. The TC4403 is built for outstanding ruggedness and reliability in harsh applications. Input voltage excursions above the supply voltage or below ground are clamped internally without damaging the device. The output stages are power MOSFETs with high-speed body diodes to prevent damage to the driver from inductive kickbacks. 2 3 4 5 6 APPLICATIONS s s s Isolated Load Drivers Pulsers Safety Interlocks ORDERING INFORMATION Part No. TC4403CPA TC4403EPA TC4403MJA Package 8-Pin PDIP 8-Pin PDIP 8-Pin CerDIP Temperature Range 0°C to 70°C – 40°C to +85°C – 55°C to +125°C PIN CONFIGURATION NC IN (VDD) GND IN (GND) 1 2 3 4 TC4403 8 7 6 5 NC OUT (VDD) VDD OUT (GND) (TOP VIEW) FUNCTIONAL BLOCK DIAGRAM 6 VDD 7 300mV INPUT HYSTERESIS 5 OUT (VDD) OUT (GND) 7 IN (GND) IN (VDD) 4 2 TC4403 GND 3 EFFECTIVE INPUT C = 20pF (EACH INPUT) TC4403-6 10/11/96 8 4-213 TELCOM SEMICONDUCTOR, INC. 1.5A HIGH-SPEED, FLOATING LOAD DRIVER TC4403 ABSOLUTE MAXIMUM RATINGS* Supply Voltage ......................................................... +22V Maximum Chip Temperature ................................. +150°C Storage Temperature Range ................ – 65°C to +150°C Lead Temperature (Soldering, 10 sec) ................. +300°C Package Thermal Resistance CerDIP, RθJ-A ............................................... 150°C/W CerDIP, RθJ-C ................................................. 50°C/W PDIP, RθJ-A .................................................. 125°C/W PDIP, RθJ-C .................................................... 42°C/W Operating Temperature Range C Version ............................................... 0°C to +70°C E Version .......................................... – 40°C to +85°C M Version ....................................... – 55°C to +125°C *Static-sensitive device.
