FEATURES
N N N N N N N N N N N 384x Series Pinout with BiCMOS Technology Zero Cross-Conduction Current by Design 1MHz Operation 65ns Maximum Current-Sense Delay 120µA Maximum Start-Up Current 1.5mA Maximum Operating Current High Output Current Drive – 1.0A, IMP38HC4x – 0.5A, IMP38C4x 20V Maximum Supply Voltage 2.5V, 1%, Trimmed Error Amplifier Reference Trimmed Oscillator Discharge Current Pin-for-Pin Enhanced Replacements for Micrel MIC38C/HC4x and GMT38C4x/HC4x – 1MHz Operation – No Cross-Conduction Current – 50ns Current-Sense Delay Notable among the improvements are zero cross-conduction/shoot-through current, reduced start-up and operating current, lower current-sense delay, higher frequency operation, full supply voltage swing at the output and a 1% trimmed voltage reference. IMP38C4x and IMP38HC4x output driver stage has zero cross-conduction current. A proprietary output state-machine monitors each output MOSFET and guarantees by design zero cross-conduction current. This is an industry first for 384x PWM devices.
