Notes
1.Exceeding these limits may cause malfunction or permanent damage to the device.
2.Maximum output clamp energy capability at 150°C junction temperature using single non-repetitive pulse method with I = 350 mA.
3.ESD1 testing is performed in accordance with the Human Body Model (C_ZAP = 100 pF, R_ZAP = 1500 ).
4.ESD2 testing is performed in accordance with the Machine Model (C_ZAP = 200 pF, R_ZAP = 0 ).
5.Maximum power dissipation at T_A = 25°C with no heatsink used.
6.Terminal soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device.

Description

The 33879 device is an 8-output hardware-configurable, high-side / low-side switch with 16-bit serial input control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33879 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33879 controls various inductive, incandescent, or LED loads by directly interfacing with a microcontroller. The circuit's innovative monitoring and protection features of 33879 include very low standby currents, cascade fault reporting, internal + 45 V clamp voltage for low-side configuration, - 20 V high-side configuration, output-specific diagnostics, and independent overtemperature protection.
