Features • 1.1 - 3.6 V Operating Voltage Range • 4 Non-inverting, Tristatable Drivers for the Following Applications: – – – – Motor Driver for Bipolar Stepper Motors in Watch/Clock Applications Driver for Piezoelectric Transducers (Buzzer) LED Driver Line Driver for Medium Speed Applications Applications • • • • • Motor Driver Radio Controlled Clock/Watch Line Driver for Mini Computer, Laptop LED Driver Relay Driver Benefits Low Voltage CMOS Driver Circuit e5130 • High Load Current at Low Supply Voltage • Replaces Several Discrete Transistors • Tri-state Operation Possible Description The e5130 contains 4 independent driver outputs with an ON resistance of typically 25 W (15 W) for the P-channel output transistors and typically 20 W (13 W) for the N-channel output transistors at a supply voltage of 1.5 V (3 V). To obtain a fast transition of the outputs even for slow rise/fall time input signals, all digital inputs (IN1 to IN4) have a Schmitt-trigger characteristic with a hysteresis of typically 50 mV. If a higher driving capability is needed, all inputs and outputs may be connected in parallel. In this case the rise/fall time of the input signals IN1 to IN4 must be less than 200 ns. Due to the fast switching characteristic of the tri-statable output drivers, the circuit is also suited as a low-voltage bus driver. 4730A–CLOCK–07/03 1 Pad Configuration Figure 1.

All inputs and outputs on circuits are highly protected against electrostatic discharges. However, precautions to minimize build-up of electrostatic charges during handling are recommended. The circuits are protected against supply voltage reversal for typically 5 minutes, if the current is limited to 120 mA.
