Data sheet
TPS4810-Q1
- AEC-Q100 automotive qualified for automotive applications
- Device temperature grade 1: –40°C to +125°C ambient operating temperature range
- Functional Safety-Capable
- 3.5V to 80V input range (100V absolute maximum)

- Two strong gate drivers (2A source and sink) for back to back MOSFET driving with separate control inputs (INP1, INP2)
- Adjustable short circuit protection (ISCP) using external Rsense or MOSFET VDS sensing with adjustable delay (TMR)
- High or low-side current sense configuration (CS_SEL)
- Fault indication (FLT) during short circuit fault, charge pump undervoltage, input undervoltage, and short-circuit comparator diagnosis (SCP_TEST)
- Adjustable input undervoltage lockout (UVLO)
- Pin-to-pin compatible with TPS1210-Q1
The TPS48100-Q1 is a 100V low IQ smart high side driver with protection and diagnostics. With wide operating voltage range of 3.5V–80V, the device is suitable for 12V, 24V, and 48V system designs. The device can withstand and protect the loads from negative supply voltages down to –65V.
It has two strong 2A (source and sink) gate drivers with separate control inputs (INP1, INP2) to drive back to back MOSFETs in common source configuration. Strong GATE driving enables power switching using parallel MOSFETs in high current system designs.
The device provides adjustable short-circuit protection. Auto-retry and latch-off fault behavior can be configured. Current sensing can be done either by an external sense resistor or by MOSFET VDS sensing. High side or low side current sense resistor configuration is possible by using CS_SEL pin input. The device also features diagnosis of the internal short circuit comparator using external control on SCP_TEST input.
A low quiescent current (35µA, typical) in operation enables always ON system designs. Quiescent current reduces to 1.5µA (typical) with EN/UVLO low.
The TPS48100-Q1 is available in a 19-pin VSSOP package.
