The HIP4020 is a half amp full bridge power driver for small 3V, 5V and 12V DC motors. This device has 4-quadrant load control function, which can change the direction of current flow by controlling the voltage between OUTA and OUTB terminals.
The HIP4020 is a half‑amp full‑bridge power driver designed for small 3 V, 5 V and 12 V DC motors. It features independent complementary MOS outputs, split‑supply operation, low standby current, and CMOS/TTL compatible input logic. Over‑temperature shutdown, over‑current limit, and fault‑flag output protect the device, while ESD‑protected inputs guard against electrostatic discharge.
Typical applications include DC motor drivers, relay and solenoid drivers, speedometer/tachometer displays, remote power switches, and battery‑operated switch circuits. The datasheet provides pinout, absolute maximum ratings, electrical specifications, performance curves, and package dimensions for the SOIC‑20 package.
| Operating Supply Voltage Range | +3 V to +12 V |
|---|---|
| Low Voltage Logic Retention Minimum | +2 V |
| Idle Supply Current (No Load, Vpp=+5 V) | 0.8 mA |
| P‑Channel rds(on) (VDD=+3 V, I=250 mA) | 1.6 Ω typical |
| N‑Channel rds(on) (VDD=+12 V, I=400 mA) | 0.5 Ω typical |
| Maximum Output Load Current (Typical) | 550 mA |
The idle supply current with no load and Vpp = +5 V is about 0.8 mA.
It operates from a typical supply voltage of +3 V to +12 V.
The driver limits the output load current to about 550 mA in typical operation.
