Infineon Technologies BTS7710GPNTMA1

Overview

BTS7710GPNTMA1 from Infineon Technologies is a high-current, dual-channel high-side power switch IC designed for 12 V automotive applications. It integrates two independent protected high-side switches in a single TO-263-15 package, each rated for 60 V absolute maximum supply voltage, 70 A peak current, and features integrated current sense with ±5% accuracy at 25 °C.

For engineers reviewing the BTS7710GPNTMA1 datasheet, BTS7710GPNTMA1 pinout, BTS7710GPNTMA1 application, or BTS7710GPNTMA1 equivalent, key selection criteria include channel independence, diagnostic feedback via analog current sense output, thermal shutdown with hysteresis, and compliance with ISO 7637-2 pulse 5a/b for load dump protection.

Technical Context

This device implements two fully independent high-side power switches using vertical DMOS technology, each with dedicated enable (INx), current sense (CSx), and status (STx) pins. Each channel supports PWM operation up to 25 kHz and provides real-time overcurrent detection with fast response time (< 2 µs).

Thermal management is enabled by an integrated junction temperature sensor and programmable thermal warning output (TW), while fault reporting includes open-load detection in OFF-state and short-to-battery detection in ON-state - all without external components.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The BTS7710GPNTMA1 specifies a maximum junction temperature of 150 °C for continuous operation. Thermal shutdown activates at 175 °C with 25 °C hysteresis, and the TW pin asserts at 150 °C to allow preemptive derating. PCB layout must provide ≥ 200 mm² of 2-oz copper connected to the exposed drain pad for sustained 25 A operation at 85 °C ambient.

Does BTS7710GPNTMA1 support PWM dimming for LED loads?

Yes - each channel supports PWM frequencies up to 25 kHz with minimal dead-time distortion and consistent on-resistance across duty cycles. The integrated current sense (0.5 V/A) enables closed-loop brightness control, and the fast fault response (< 2 µs) prevents LED damage during short-circuit events in high-brightness configurations.

How is open-load detection implemented in the OFF-state?

Open-load detection operates by applying a small test current (~100 µA) through the channel's internal pull-down circuitry when INx = LOW. If no return path to GND is detected (i.e., floating or disconnected load), STx goes low after 100 µs, signaling an open-circuit condition - independent of load type or external components.

Can BTS7710GPNTMA1 be used in 24 V commercial vehicle systems?

It is qualified for 12 V automotive systems per AEC-Q100 Grade 1 (−40 °C to +125 °C), with 60 V absolute maximum V_BB. While it withstands 24 V nominal rails, its current rating derates above 16 V due to increased conduction loss; use in 24 V systems requires thermal validation and is not recommended without Infineon's specific qualification data for that voltage class.
