1 Features

• AEC-Q100 automotive qualified for grade 1

temperature

• 3.5V to 73V input range (74V absolute maximum)

• Reverse input protection down to –65V

– TPS12141-Q1 with reverse FET ON (–45V)

• Integrated 12V charge pump

• Low IQ = 20μA in low power mode (LPM = Low)

• Low 1μA shutdown current (EN/UVLO = Low)

• Dual gate drive: GATE: 0.5A source and 2A sink

G: 100μA source and 0.39A sink

• Accurate I2t overcurrent protection (IOC) with

adjustable circuit breaker timer (I2t)

• Accurate and fast (5μs) short-circuit protection

to active mode using adjustable load wakeup

threshold or LPM trigger with WAKE indication

• Accurate analog current monitor output (IMON):

±2% at 30mV VSNS

• NTC based overtemperature sensing (TMP) and

monitoring output (ITMPO)

• Fault indication (FLT) during short circuit fault, I2t,

charge pump UVLO

• TPS12142-Q1 (RPP turn OFF), TPS12143-Q1

(RPP turn ON) with I2t disabled

3 Description

TPS1214-Q1 is a family of low IQ smart high side

drivers with protection and diagnostics. With wide

operating voltage range of 3.5V to 73V and a 74V

absolute maximum rating the device is suitable for

12V, 24V, and 48V automotive system designs.

It has two integrated gate drives with 0.5A source and

2A sink (GATE) and 100μA source and 0.39A sink

(G). With LPM Low, the low power path is kept ON

and the main FETs are turned OFF with IQ of 20μA

(typ). Auto load wakeup threshold adjusted using

RBYPASS resistor placed across CS2+ and CS2–. IQ

reduces to 1μA (typ) with EN/UVLO low.

The device has accurate current sensing (±2%) output

(IMON) with adjustable I2t based overcurrent and

short circuit protection using an external RSNS resistor

and FLT indication. Auto-retry and latch-off fault

behavior can be configured. The device also has NTC

based temperature sensing (TMP) and monitoring

output (ITMPO) output for overtemperature detection

of external FETs.

The TPS1214-Q1 is available in 23-pin VQFN

package.
